2 MENUBAR AND TOOLBAR

This section briefly reviews the menus and commands in order to understand the basic purpose of each.

The toolbar is displayed across the top of the application window, below the menu bar. The toolbar provides quick mouse access to many tools used in Global Mapper. To hide or display the toolbars or to switch to the old Toolbar display, which some users prefer, use the View menu commands for the toolbar.

Menu Headings File Menu

The File menu offers the following commands:

Open Data File(s) Command

The Open Data File(s) command allows the user to open additional data files into the main Global Mapper view. If no other data is already loaded and the user has not explicitly set a projection, the view will adopt the projection and datum of the first data file selected for loading. If other data is already loaded, the selected data files will be displayed in the current projection/datum.

The data will automatically be displayed at the proper location relative to other loaded data, creating a mosaic of data that is properly placed spatially. You don't have to do anything special to create mosaics of multiple files, this happens simply by loading the geo-referenced files into Global Mapper.

Note: Global Mapper automatically opens files with tar.gz extensions without the use of a decompression tool such as Winzip. This is particularly useful for SDTS transfers, which are typically distributed in a .tar.gz format.

Open Generic ASCII Text File(s) Command

The Open Generic ASCII Text File(s) command allows the user to import data from a wide variety of generic ASCII text formats.

Selecting the Open Generic ASCII Text File command prompts the user to select the file(s) to load and then displays the Generic ASCII Text Import Options dialog (pictured below). This dialog allows the user to specify how the text file(s) are formatted so that they can be imported.

Global Mapper supports coordinates in decimal format as well as degree/minute and degree/minute/second coordinates.


The Import Type section allows the user to specify how they want the data in the file to be treated. The different import types are defined as follows:

The Coordinate Column Order section allows the user to specify in what order the coordinates are found on coordinate lines in the file. Coordinates can either be x followed by y (i.e. longitude then latitude) or the reverse. Elevation values, if any, are always assumed to come after the x and y values. The Fields to Skip at Start of Line setting controls what field index (column) the coordinates start in. For example, if the x and y coordinates are in the 3rd and 4th columns, set this value to 2 so that the coordinates will be grabbed from the appropriate place. The Coordinate Format option allows you to specify how coordinate values are stored. The default option supports several formats, including using the exact decimal representation for the coordinate and automatic recognition of separated latitude/longitude degree values, such as DD MM SS with a large variety of supported separating characters. Support also exists for packed decimal degree values in the formats DDMMSS.S and DDMM.M.

The Coordinate Delimeter section allows the user to specify what character the coordinates are separated by on coordinate lines. If the Auto-Detect option is selected, Global Mapper will attempt to automatically determine the coordinate delimeter. This option will usually work and should probably be used unless you have trouble.

The Coordinate Line Prefix section allows the user to specify whether coordinates start at the beginning of the line or if coordinate lines start with some other sequence of characters. For example, some formats may start coordinate lines with the sequence "XY,".

The Rows to Skip at Start of File setting controls how many lines to skip at the start of the file before trying to extract data. This is useful if you have some header lines at the start of your file that you want to skip over.

The Feature Classification section allows the user to specify what feature type to assign to area, line, and point features imported from the file.

If the Include attributes from lines with coordinate data option is selected, any text found AFTER the coordinate data on a line from the file will be including as attribute for the feature that coordinate is in. If not selected, only lines from the file that are not determined to contain coordinate data will be used as attributes.

If you are doing a Point Only import and the Column Headers in First Row of File option is checked, values in the first line from the file will be used at the names of attributes for attributes found in coordinate data lines. This is useful for things like CSV files.

If the Treat 3rd coordinate value as elevation option is selected and a numeric value is found immediately following the x and y (or lat and lon) coordinate values, that value will be treated as an elevation. Otherwise, the value will be included as an attribute if the Include attributes from lines with coordinate data option is selected. Typically you want to leave this option checked unless you are importing point data in which the 3rd column is an attribute that occasionally contains all numeric values, such as well names.

If you have line and/or area data that do not have non-coordinate lines separating them but rather are delimited by a change in a particular field/column of data, you can use the Break Line/Area Features on Change in Field option to specify which field (use a 1-based index) to check for breaking the data into separate line/area features.

Pressing the Select Coordinate Offset/Scale button displays a dialog that allows the user to select an offset and scale factor to apply to each coordinate. The offset entered will first be added to each coordinate, and then each coordinate will be multiplied by the scale factor.

When generic ASCII text files are imported, Global Mapper will scan the attributes associated with each feature and look for any attribute names that are known to it. The following is an abbreviated list of attribute names that are currently recognized by Global Mapper when generic ASCII text files are read (see the links below the list for more complete lists):

Click here for more instructions on creating generic ASCII data files with features of various types and click here for more documentation on the supported fields.


Download Online Imagery/Topo/Terrain Maps

The Download Online Imagery/Topo/Terrain Maps command allows the user to download mapping data from numerous built-in and user-supplied sources. This includes premium access to high resolution color imagery for the entire world from DigitalGlobe, worldwide street maps from OpenStreetMap.org, as well as seamless USGS topographic maps and satellite imagery for the entire United States from MSRMaps.com/TerraServer-USA. In addition, access is provided to several built-in WMS (OpenGC Web Map Server) databases to provide easy access to digitial terrain data (NED and SRTM) as well as color satellite imagery (Landsat7) for the entire world. You can also add your own WMS data sources for access to any data published on a WMS server.

This is an extremely powerful feature as it puts many terabytes of usually very expensive data right at your fingertips in Global Mapper for no additional cost (with the exception of access to the un-watermarked DigitalGlobe imagery, which is not free). Note that this feature requires Internet access to work.

When you select the menu command, the Select Online Data Source to Download dialog (pictured below) is displayed. This dialog allows you to select the type, or theme, of data to download, as well as the extents of the data to download. You can either select to download the current screen bounds, an area to download around an address, specify a lat/lon bounds explicitly, or select to download the entire data source.


Once the data to download is defined, Global Mapper will automatically download the most appropriate layer for display as you zoom in and out. This way, you can see an overview of the data when zoomed out, with more detail becoming available when you zoom in. You can also export this data in full resolution to any of the supported raster export formats, such as GeoTIFF, JPG, or ECW. The most appropriate detail level for the export sample spacing will be used to obtain the source data for the export.

Each data source load will appear as a separate layer in the Overlay Control Center. Each entry can have it's display options modified just like any other raster layer to drape it over elevation data, blend it with other layers, etc.

You can use the Add New Source button to add new online sources of imagery from WMS (Web Map Service), WCE (Web Coverage Service), OSM (OpenStreetMap Tiles), Google Maps-organized tiles or TMS (Tile Map Service) sources. When you press the button a dialog appears allowing you to choose the type of source to add. If you select the WMS or WCS option then the Select WMS Data Source to Load dialog (pictured below) is displayed. This dialog allows you to specify the URL of a WMS or WCS data source and select what layer(s) to add as an available data source on the Select Online Data Source to Download dialog. The URL that you should specify is the GetCapabilities URL, such as http://wms.jpl.nasa.gov/wms.cgi for the JPL WMS data server. Once you've entered the URL, press the Get List of Available Data Layers button to query the server and populate the data control with the available data layers on that server. Then simply select the data layer and style that you want and press OK to have it added to the available data source list. Once a source is added, you can use the Remove Source button to remove it from the list of available data sources at a later time. If you need to specify additional options for the WMS server, such as forcing a particular image format to be used, add those parameters after the Service Name parameter. For example, to force the use of the JPG format, you might specify a Service Name parameter of 'WMS&format=image/jpeg'. To force a particular projection that the server supports to be used, include a SRS parameter, like 'WMS&SRS=EPSG:26905' to force the use of the UTM projection with the NAD83 datum and zone 5N.

You can also right-click on the added WMS layer in the list of sources and set a maximum zoom level (in meters per pixel) for the layer. For example you can specify a maximum zoom level of 5.0 meters per pixel, so when loading data from the source no tiles with a resolution greater than 5.0 meters per pixel will be downloaded. This is useful for sources that don't specify themselves what the maximum resolution should be and just go blank when you overzoom them.



If you choose the OSM, Google Maps, or TMS source type, then the OSM/TMS Tile Source Defintion dialog (pictured below) is displayed, allowing you to setup the source. You need to specify the base URL where the data for the tiled source can be found (this should be the folder under which the folders for each zoom level are stored). You can also provide a URL with variables named %x (column), %y (row), and %z (zoom scale) in the URL so that you can setup the URL however your data source requires rather than using the default expected URL setup. You also must select whether the source uses PNG or JPG image files and provide the maximum zoom level and bounds of the data source.



You can also use the Delete Cached Files button to remove any locally cached files from any particular type of data sources. This is useful if the online data may have changed or if you have downloaded corrupt files somehow.

The Add Sources From File button allows you to add new WMS sources from an external text file. This provides an easy way to share your list of WMS sources with other users. You can simply provide them with your wms_user_sources.txt file from your Application Data folder (see the Help->About dialog for the location of this folder) and they can load that file with this button to add their sources to your source list.


Open All Files in a Directory Tree Command

The Open All Files in a Directory Tree command allows the user to open all of the files matching a user-specified filename mask under a user-selected directory. You will first be prompted to select a folder from which to load the files. After selecting the folder, you will be prompted to enter a filename mask for all of the files that you would like to attempt to load. After selecting a filename mask, all files under the selected folder which match the filename mask and are recognized by Global Mapper as a known data type will be loaded.

The filename mask supports the * and ? wildcard characters. The default mask of * will check all files under the selected folder. You can also cause data to only be loaded from selected folders as well. For example, if you had a large collection of folders with data split up into 1x1 degree blocks with the folder names depecting the 1x1 degree block they held, you could use a directory name mask to load only those blocks that you wanted. For example, you might use a mask of N4?W10?\*.tif to load all TIFF files between N40 and N50 and W110 and W100.

You can also specify multiple masks if you need more than one to describe the set of files that you would like to load. Simply separate the masks with a space.

Open ECW File from the Web Command

The Open ECW File from the Web command allows the user to open an ER Mapper Compressed Wavelet (ECW) image file directly from an Image Web Server URL. While these files may be terabytes in actual size, only the portion needed for the current display window is downloaded, allowing for the browsing of extremely large data sets.

Selecting the Open ECW File from the Web command displays the Load Image From Web dialog (pictured below). This dialog allows the user to either select a predefined web link for loading or to enter the URL of any available ECW file served by Image Web Server.


The tree on the left of the dialog allows the user to select which data file they wish to load. Global Mapper comes with several dozen useful links already entered into the tree.

To access your own ECW image from the web, press the Add Link... button. This button causes the Add New Web Link dialog (pictured below) to be displayed.


The Group Name drop list allows the user to select which group, if any, to place the new link in. Any of the predefined groups can be selected, or a new group name can be entered. Leaving the group name blank will cause the new link to appear at the root level of the tree.

The Description field is where you enter the human-readable description of the link. This is what will be displayed for the link on the main dialog. Leaving this blank will cause the URL to be displayed instead.

The URL field is the most important piece of this dialog. This is where you specify the address of the ECW file to load. The URL should begin with the prefix ecwp:// with the remainder being a valid path to an ECW file served using ER Mapper's Image Web Server software.

When you've completed entering information about the new web link, press the OK button to complete your entry and have it added to the web link tree in the Load Image From Web dialog.

Pressing the Edit Link... button allows the user to edit the currently selected web link. Note that the built-in web links cannot be edited.

Pressing the Delete Link... button will delete the currently selected web link or group from the web link tree.

If you get an error message indicating that your settings have been updated to support the ECWP protocol whenever you try to load an ECW layer from the web you need to download and install the latest ECW ActiveX plugin from http://demo.ermapper.com/ecwplugins/DownloadIEPlugin.htm.

Open Data File at Fixed Screen Location

The Open Data File at Fixed Screen Location command allows the user to open any supported data file format for display at a fixed location on the screen rather than at a fixed location on the earth. This is particularly useful for loading things like bitmaps for legends and logos. The loaded data will be used for screen display, export, and printing operations.

Selecting the Open Data File at Fixed Screen Location command first prompts you to select a file to load, then displays the Fixed Screen Location Setup dialog (pictured below). This dialog allows the user to specify the size and position of the data relative to the screen/export/printout.



Unload All Command

The Unload All command unloads all overlays and clears the screen.

Create New Map Catalog Command

The Create New Map Catalog command allows you to create a "map catalog". A "map catalog" is a collection of map files which are grouped together to allow for easy loading, viewing, and export. Layers in a map catalog will be loaded and unloaded as needed for display and export, potentially greatly reducing the load time and memory requirements for working with very large collections of data.

Upon selecting this command and selecting the file to save the map catalog to, the Modify Map Catalog dialog (shown below) will be displayed, allowing you to add files to the catalog, control at what zoom level data layers are loaded for display, and setup how the map bounding boxes are displayed when you are zoomed out too far for the actual map data to display. By default map bounding boxes are displayed using the style set for the Map Catalog Layer Bounds type.


You can obtain metadata and projection information about layers in the map catalog by right-clicking on them in the Map List and selecting the appropriate option.

You can modify map catalogs again after loading them by opening the Overlay Control Center, selecting the map catalog layer, then pressing the Options button.

Note: Only registered users of Global Mapper are able to create map catalogs.

Load Workspace Command

The Load Workspace command allows the user to load a Global Mapper workspace file (.gsw) previously saved with the Save Workspace command.

Note: Only registered users of Global Mapper are able to load Global Mapper workspace files.

Save Workspace Command

The Save Workspace command allows the user to save their current set of loaded overlays to a Global Mapper workspace file for later loading with the Load Workspace command.

The Global Mapper workspace maintains the list of all currently loaded overlays as well as some state information about each of those overlays. When the workspace file is loaded, all of the overlays that were loaded at the time the workspace file was saved will be loaded into Global Mapper. This provides a handy way to easily load a group of overlays which you work with often.

The Global Mapper workspace will also contain any changes that you have made to loaded vector features as well as any new vector features that you have created. The user projection and last view on the data will also be maintained.

Find Data Online Command

Selecting the Find Data Online command will open a web browser pointing to places on the internet where data compatible with Global Mapper is available for download.

Run Script Command

The Run Script command allows users to run a Global Mapper script file that they have created. This is a powerful option that allows the user to automate a wide variety of tasks. Click here for a guide to the scripting language.

Selecting the Run Script command from the menu displays the Script Processing dialog, shown here.


The Script File pane displays the currently loaded script file. To load a new script file for processing, press the Load Script... button at the bottom left corner of the dialog.

If you would like the script file to make use of data already loaded in the main view and to also affect what is displayed in the main view, check the Run Script in the Context of the Main View option prior to running the script.

To run the loaded script file, press the Run Script button. Any warning, error, or status messages generated while running the script will be output to the Script Results pane.

When you are done processing scripts, press the Cancel button to close the dialog.

Note: Only registered users of Global Mapper are able to run Global Mapper script files.

Capture Screen Contents to Image Command

The Capture Screen Contents to Image command allows user to save the current contents of the Global Mapper window to a JPEG, PNG, (Geo)TIFF, or Windows Bitmap (BMP) file. In addition, the generated image can be generated in a higher resolution than the screen to provide greater fidelity. Also, a world file for georeferencing in other software packages as well as a projection (PRJ) file describing the native ground reference system of the image can be optionally generated as well.

Unlike the raster export commands described later, the Capture Screen Contents to Image command also saves any vector overlays drawn to the screen.

Selecting the Capture Screen Contents to Image command from the menu displays the Screen Capture Options dialog, shown here.


The Image Format section allows the user to select the format of the image to generate. Different formats have their own unique strenghts and weaknesses which make choosing the best format vary depending on the desired end results. The supported formats are:

The width and height of the generated image in pixels are specified in the Image Size panel. By default, the size of the Global Mapper view pane are used. Using these values will generate an image that exactly matches what you see. You can change these values to generate a more or less resolute image with the obvious tradeoff of size vs. quality.

Checking the Generate World File option results in a world file being generated in addition to the image. The world file will be generated in the same directory as the image and will have the same primary name as the image. The filename extension will depend on the selected image type (JPEG=.jpgw, PNG=.pngw, TIFF=.tfw,BMP=.bmpw).

Checking the Generate Projection (PRJ) File option results in a projection file being generated describing the ground reference system of the created image. The projection file will be generated in the same directory as the image and will have the same primary name as the image with an extension of .prj.

Checking the Generate Text Metadata File option results in a text file being generated listing the metadata for the captured image.

Checking the Crop to Loaded Map Data option results in a text file being generated that is cropped to the bounds of your currently loaded map data rather than the full screen extents. If the loaded map data does not take up at least the entire screen then your specified pixel dimensions will also be shrunk so that the pixel size remains the same.

Pressing the OK button prompts the user to select the name and location of the image to generate and then proceeds to generate the image.

Note: Only registered users of Global Mapper are able capture the screen to an image file.

Export Global Mapper Package File Command

The Export Global Mapper Package File command allows the user to export any or all of the loaded data to a Global Mapper package file. These files are similar to workspace files except that the actual data is stored in the files. Package files provide an easy way to pass around lots of data between Global Mapper users on different computers with a single self-contained file.

When selected, the command displays the Global Mapper Package Export Options dialog which allows the user to setup the package export. The dialog consists of a Package Options panel, a Simplification panel, a Gridding panel, and an Export Bounds panel.


The Package Options panel consists of options allowing the user to select the projection to save the data in, how to handle dynamically streamed MSRMaps.com/TerraServer-USA data, and other options. These include the Always Maintain Feature Styles option, which specifies that any vector features stored in the package file should explicitly save the styling of that feature, even if they are using the default style for the feature classification. This can make it easier to maintain exact styling when transferring packages between Global Mapper installations.

In the Projection section of the panel, the user can choose to save all loaded data in the currently selected view projection (this is the projection selected on the Projection tab of the Configuration dialog), in latitude/longitude coordinates (the "Geographic" projection) with the WGS84 datum, or to keep each layer in its original native projection.

In the TerraServer Export Options section of the panel, the user can select how displayed layers from the Download TerraServer menu option are exported. The Automatic selection for imagery themes (i.e. DOQs, Urban Area imagery) will save data slightly more detailed than what is displayed on the screen. For the DRG (topographic map) theme, the most detailed zoom range for the current scale of DRG map being displayed (i.e. 24K, 100K, 250K) will be determined and data from that scale will be saved. The other alternatives either save the most detailed scale available, creating potentially very large files, or the scale the most closely matches the current display scale on the screen.

The Combine Compatible Vector Layers into a Single Layer option causes all vector features with the same native projection to be combined into a single layer within the package file rather than maintaining their original layer structure.

The Embed Images Associated with Picture Points option causes any images associated with a vector feature (like points from an EXIF JPEG file) to be embedded in the GMP file for easy use on other systems.

The Simplification panel allows the user to set up the threshold at which points that don't contribute much to the shape of the vector line and area features being exported are removed in order to generate features with less vertices. By default, all vertices will be kept, but the user can move the slider to the right to get rid of relatively insignificant vertices and realize significant space spacings at the cost of some fidelity.

The Gridding panel allows the user to split up the data into regularly spaced tiles on export if desired rather than just exporting a single file.

The Export Bounds panel allows the user to select what portion of the loaded data they wish to export.

Note: Only registered users of Global Mapper are able capture the screen to an image file.

Export PDF/GeoPDF File Command

The Export PDF File command allows the user to export any or all of the loaded data to a Geo-enabled PDF file. These are standard PDF files that can be read in Adobe Acrobat Reader. They also will have geopositioning information embedded in them so that mapping applications like Global Mapper can automatically display the data in the PDF at the proper location.

When selected, the command displays the PDF Export Options dialog which allows the user to setup the PDF export. The dialog consists of a PDF Options panel, a Gridding panel, and an Export Bounds panel.


The PDF Options tab allows the user to setup the PDF-specific export options. The following sections are available:

If any of the point features being exported contain an attribute with LINK in the attribute name and a value either pointing to a valid web URL or a local file, then a clickable hot-spot will be embedded in the generated PDF file allowing you to click the location and pull up the web page or file from inside Acrobat Reader.

The Gridding panel allows the user to split up the data into regularly spaced tiles on export if desired rather than just exporting a single file.

The Export Bounds panel allows the user to select what portion of the loaded data they wish to export.

Note: Only registered users of Global Mapper are able capture the screen to an image file.

Export Raster and Elevation Data

The commands on the Export Raster and Elevation Data submenu allow the user to export loaded raster and elevation data to various formats.

Export Arc ASCII Grid Command

The Export Arc ASCII Grid command allows the user to export any loaded elevation grid data sets to an Arc ASCII Grid format file.

When selected, the command displays the Arc ASCII Grid Export Options dialog which allows the user to setup the export. The dialog consists of a General options panel which allows the user to set up the grid spacing and vertical units, a Gridding panel and an Export Bounds panel which allows the user to set up the portion of the loaded data they wish to export.

Note: Only registered users of Global Mapper are able to export data to any format.

Export BIL/BIP/BSQ Command

The Export BIL/BIP/BSQ command allows the user to export any loaded raster, vector, and/or elevation grid data to a BIL, BIP, or BSQ format file.

When selected, the command displays the BIL/BIP/BSQ Export Options dialog which allows the user to setup the export. The dialog consists of an Options panel (pictured below), which allows the user to set up type of export to perform, the sample spacing, vertical units, and other applicable options, a Gridding Panel, and an Export Bounds panel which allows the user to set up the portion of the loaded data they wish to export.


Note: Only registered users of Global Mapper are able to export data to any format.

Export BMP Command

The Export BMP command allows the user to export any loaded raster, vector, and elevation grid data sets to a 24-bit RGB BMP file.

When selected, the command displays the BMP Export Options dialog which allows the user to setup the export. The dialog consists of a General options panel which allows the user to set up the pixel spacing, a Gridding panel, and an Export Bounds panel which allows the user to set up the portion of the loaded data they wish to export.

Note: Only registered users of Global Mapper are able to export data to any format.

Export BSB Marine Chart Command

The Export BSB Marine Chart command allows the user to export any loaded raster, vector, and elevation grid data sets to a palette-based (up to 127 colors) BSB marine chart raster image for use in compatible applications and some marine chartplotters. The export will generate a single KAP file containing the chart image.

When selected, the command displays the BSB Export Options dialog which allows the user to setup the export. The dialog consists of a General options panel which allows the user to set up the pixel spacing and chart parameters, a Gridding panel, and an Export Bounds panel which allows the user to set up the portion of the loaded data they wish to export.

Note: Only registered users of Global Mapper are able to export data to any format.

Export BT (Binary Terrain) Command

The Export BT (Binary Terrain) command allows the user to export any loaded elevation grid data sets to a BT (Binary Terrain) format file.

When selected, the command displays the BT (Binary Terrain) Export Options dialog which allows the user to setup the export. The dialog consists of a General options panel which allows the user to set up the grid spacing to use, a Gridding panel, and an Export Bounds panel which allows the user to set up the portion of the loaded data they wish to export.

Note: Only registered users of Global Mapper are able to export data to any format.

Export DEM Command

The Export DEM command allows the user to export any loaded elevation grid data sets to a native format USGS DEM file.

When selected, the command displays the DEM Export Options dialog which allows the user to setup the export. The dialog consists of a General options panel which allows the user to set up the quadrangle name, grid spacing and vertical units, a Gridding panel, and an Export Bounds panel which allows the user to set up the portion of the loaded data they wish to export.

Note: Only registered users of Global Mapper are able to export data to any format.

Export DTED Command

The Export DTED command allows the user to export any loaded elevation grid data sets to native format DTED files. DTED files support a set of fixed resolutions (i.e. DTED levels) which are defined as aligning on particular boundaries. When you select the DTED level to export to and the export bounds, this defines which DTED tiles need to be generated to conform to the DTED standards for that level. The filename that you select for the export is used as a base, with the lat/lon coordinates of the southwest corner of each tile appended to each filename as it is exported. You can also option choose to split up the exports by longitude into separate folders, in which case the longitude is used as a folder name and the latitude appended to your base filename for each exported cell.

When selected, the command displays the DTED Export Options dialog which allows the user to setup the export. The dialog consists of a DTED Options panel which allows the user to set up the DTED level and other options, a Gridding panel, and an Export Bounds panel which allows the user to set up the portion of the loaded data they wish to export.

ADVANCED USERS: You can change the accuracy value exported in DTED files by specifying your own string value (up to 4 characters in length) at "HKEY_CURRENT_USER\Software\Global Mapper\DTEDAccuracy". The collection system value (up to 12 characters in length) can be specified at "HKEY_CURRENT_USER\Software\Global Mapper\DTEDCollectionSystem".

Note: Only registered users of Global Mapper are able to export data to any format.

Export DXF 3D Face File Command

The Export DXF 3D Face File command allows the user to export any loaded gridded elevation data sets to a DXF 3D Face file.

When selected, the command displays the DXF 3D Face Export Options dialog which allows the user to setup the export. The dialog consists of a General options panel which allows the user to set up the grid spacing and vertical units, a Gridding panel, and an Export Bounds panel which allows the user to set up the portion of the loaded data they wish to export.

Note: Only registered users of Global Mapper are able to export data to any format.

Export DXF Mesh Command

The Export DXF Mesh command allows the user to export any loaded elevation grid data sets to a 3D DXF Mesh file.

When selected, the command displays the DXF Mesh Export Options dialog which allows the user to setup the export. The dialog consists of a General options panel which allows the user to set up the grid spacing and vertical units, a Gridding panel, and an Export Bounds panel which allows the user to set up the portion of the loaded data they wish to export.

Note: Only registered users of Global Mapper are able to export data to any format.

Export DXF Point Command

The Export DXF Point command allows the user to export any loaded elevation grid data sets to a 3D DXF Point file. The DXF file will consist of a 3D DXF point for each point in the elevation grid defined by the spacing and extents that the user specifies. This option may be useful when used with other software packages that do not specify the DXF mesh format.

When selected, the command displays the 3D DXF Point Export Options dialog which allows the user to setup the export. The dialog consists of a General options panel which allows the user to set up the grid spacing and vertical units, a Gridding panel, and an Export Bounds panel which allows the user to set up the portion of the loaded data they wish to export.

Note: Only registered users of Global Mapper are able to export data to any format.

Export ECW Command

The Export ECW command allows the user to export any loaded raster, vector, and elevation grid data sets to an ECW file. ECW files are highly compressed and great for storing things like satellite imagery. There is no size restriction on exported ECW files, so you can store many terabytes worth of imagery within a single highly compressed ECW file.

When selected, the command displays the ECW Export Options dialog which allows the user to setup the export. The dialog consists of a General options panel which allows the user to set up the pixel spacing and target compression ration, a Gridding panel, and an Export Bounds panel which allows the user to set up the portion of the loaded data they wish to export. If you would like to generate a lossless JPG2000 format file, simply slide the Target Compression Ratio slider all the way to the left (1:1 target compression ration).

Note: Only registered users of Global Mapper are able to export data to any format.

Export Erdas Imagine Command

The Export Erdas Imagine command allows the user to export any loaded raster, vector,and elevation grid data sets to an Erdas Imagine file.

When selected, the command displays the Erdas Imagine Export Options dialog which allows the user to setup the export. The dialog consists of a General options panel which allows the user to set up the pixel spacing and format, a Gridding panel, and an Export Bounds panel which allows the user to set up the portion of the loaded data they wish to export.

Note: Only registered users of Global Mapper are able to export data to any format.

Export Float/Grid Command

The Export Float/Grid command allows the user to export any loaded elevation grid data sets to a Float/Grid format file. The Float/Grid file will consist of a 4-byte IEEE floating point number for each elevation sample in the file, starting at the top-left corner and proceeding across, then down. In addition to the elevation data file, an ESRI-format .hdr file and .prj file will also be generated. There is also an option to allow exporting slope values (in degrees or percent slope if selected) or slope directions (in bearings where 0 is north, 90 is east, etc.) rather than elevation values at each sample location.

Export GeoTIFF Command

The Export GeoTIFF command allows the user to export any loaded raster, vector, and elevation data sets to a GeoTIFF format file.

When selected, the command displays the GeoTIFF Export Options dialog (pictured below) which allows the user to set up the export. The dialog consists of a GeoTIFF Options panel, a Gridding panel, and an Export Bounds panel which allows the user to set up the portion of the loaded vector data they wish to export.


The File Type section allows you to choose what type of GeoTIFF file to generate. The various file types are described below:

When generating a 256 color (8-bits per pixel) GeoTIFF, it is necessary to select a palette indicates what 256 colors will be used to describe the image being exported. The following choices of palette are available:

The Vertical Units field allows the user to select the vertical units to use when exporting elevation data (i.e. meters or feet). Any input data not in the selected vertical units will be automatically converted on export.

The Resolution section allows the user to selected the grid spacing to use when generating the GeoTIFF. The default value is the average of the grid spacings of all the currently loaded raster and elevation overlays. If the Always Generate Square Pixels option is checked, the smaller of the specified x and y resolutions will be used for both the x and y resolution. Forcing square pixels ensures that the resultant GeoTIFF file will look good even in software that is not able to deal with pixels that aren't square. If you'd like to specify the spacing in units other than those of the currently selected view/export projection, press the Click Here to Calculate Spacing in Other Units button.

If you want to generate a GeoTIFF file corresponding to a particular scale relative to the selected DPI value (see below), you can check the Export at the Fixed Scale option and then specify the scale to use. For example, if you specify a scale value of 25000, each inch in the output (an inch being the number of pixels equal to the specified DPI value) will be approximately equivalent to 25,000 inches on the ground.

The DPI Value to Save in Image option allows you to specify a DPI (dots per inch) value to save in the TIFF header. Some software, in particular graphics editing software, makes use of this value when sizing TIFF files for printout. Specifying the default value of 0 will result in the DPI tag not being saved to the TIFF file at all.

The Compression selection allows you to select what type of compression to use for the selected export file type. The available compression types are as follows:

If the Make Background (Void) Pixels Transparent option is checked for 8-bit palette, 24-bit RGB, or JPEG-in-TIFF files, an alpha channel will be added to the created GeoTIFF file to indicate which pixels should be treated as transparent. Note that this will create a larger file and not all applications will support TIFF files with alpha channels.

If the ADVANCED: Use Tile Rather than Strip Orientation option is checked, the GeoTIFF file will use a tile-based organization rather than a strip/scanline-based orientation. A tile-based orientation has advantages when zoomed in on a layer for display, but can be slower when zoomed further out. By default a tile size of 128x128 will be used, but you can customize this by creating a DWORD registry key value 'HKEY_CURRENT_USER\Software\Global Mapper\GeoTIFFExport_TileSize' with the desired tile size (like 256 for example for 256x256 tiles).

If the Save Scale/Elevation Legend/Grid if Displayed option is checked, the distance scale, elevation legend, and coordinate grid will be saved to the GeoTIFF file (except vertical GeoTIFFs) if they are configured to show up in the main display.

If the Save Vector Data if Displayed option is checked, any loaded vector data that is configured to show up in the main display will be saved to the GeoTIFF file (except vertical GeoTIFFs).

If the Generate TFW File option is checked a TIFF world file will be generated with the same name as the GeoTIFF file with a .tfw extension. The TFW file is used by software that is not capable of reading the placement of the GeoTIFF file directly from the GeoTIFF header.

If the Interpolate to Fill Small Gaps in Data option is checked, any small areas with missing data will be filled in by interpolating the surrounding valid data. This is useful for filling small gaps between adjacent tiles or small holes in elevation data.

If the Generate PRJ File option is checked a describing the projection of the coordinates in the file will automatically be created

If the ADVANCED: Don't Write GeoTIFF Header option is checked no GeoTIFF tags will be written to the generated file. This is useful for using things like datum specializations that can’t be exactly stored in GeoTIFF files, so you’d rather just use a PRJ file and not have anything in the GeoTIFF file.

If the Generate Tags for Feature Attributes option is checked, any attributes associated with exported features will be saved as tags in the resulting file. Note that this can significantly slow down your export in some cases. If the Set Global Origin to the Lower Left of Design Plane Rather than the Center of the Design Plane option is set, the global origin is set to the minimum valid negative values rather than at (0,0) as is standard. If the Replace Dark Line Colors with White option is set, any lines that are near black in color will be replaced with a white line automatically. This is useful for getting dark colored lines to show up when the exported DGN file is viewed in an application that uses a black background.

Note: Only registered users of Global Mapper are able to export data to any format.

Export DLG-O Command

The Export DLG-O command allows the user to export any loaded vector data sets to a native format USGS DLG-O (Digital Line Graph Optional format) file.

When selected, the command displays the DLG-O Export Options dialog (pictured below) which allows the user to set up the export. The dialog consists of a DLG-O Options panel which allows the user to set up the banner name, DCU (digital cartographic unit or quad name), and category name, a Gridding panel, and an Export Bounds panel which allows the user to set up the portion of the loaded vector data they wish to export. If possible, the fields on the DLG-O Options panel are automatically filled in with the best guesses available based on the currently loaded data. The user is free to change the values to fit their needs.


Note: Only registered users of Global Mapper are able to export data to any format.

Export DXF Command

The Export DXF command allows the user to export any loaded vector data sets to an AutoCAD DXF format file.

When selected, the command displays the DXF Export Options dialog (pictured below) which allows the user to set up the export. The dialog consists of a DXF Options panel, a Gridding panel, and an Export Bounds panel which allows the user to set up the portion of the loaded vector data they wish to export.


The Display Labels section allows you to control if you want feature display labels included in the DXF files and, if so, whether you want them represented as TEXT entities in their own layer (called FEATURE_LABEL) or as DXF attributes. The default is to have them included as attributes associated with each feature. As some software packages cannot handle attributes in DXF files, you may have to switch to a different option (with the associated loss of information) to get your exported DXF files to work with some software packages. If you would like line features to have rotated labels running along the line associated with them, you have to use the option to Include Display Labels as Separate Text Layer.

The Layer Names section allows you to control how the layer names used in the exported DXF file are generated. You can choose to use the feature description, feature display label, or feature source filename as the layer name in the exported file. If you choose to use the display label as the layer name, any features that do not have a display label will use the feature description as the layer name in the exported file.

If selected, the Generate Projection (PRJ) File option causes a projection file describing the ground reference system of the DXF file to be generated in addition to the DXF file itself. The PRJ file will have the same name as the DXF file with the .prj extension.

If selected, the Create 3D Features Using Loaded Elevation Data option will cause any underlying elevation data (like DEMs) to be used to retrieve elevation values for 2D features being exported and generate new 3D features in the exported DXF file. The units used by the elevation values are determined by the Elevation Display/Export Units setting on the Vertical Options tab of the Configuration dialog.

If selected, the Generate ECEF Coordinates option will cause the exported DXF file to use Earth-Centered Earth-Fixed (ECEF) XYZ coordinate values rather than XY values in the current export projection.

If selected, the Generate Zero-Width Lines option causes and line features created in the DXF file to be marked as having zero width. Use this option if you intend to use the resulting DXF file with a product such as MicroStation which has problems with lines of non-zero thickness.

Note that if you export features of the TIN Face Area area type they will be exported as 3D Face features in the generated DXF file rather than 3D polylines, allowing you to easily get a usable TIN surface for use in other applications, like 3DS Max.

Note: Only registered users of Global Mapper are able to export data to any format.

Export DWG Command

The Export DWG command allows the user to export any loaded vector data sets to an AutoCAD Drawing (DWG) format file.

The DWG Version section allows you to select which DWG version to create.

The Display Labels section allows you to control if you want feature display labels included in the DWG files and, if so, whether you want them represented as TEXT entities in their own layer (called FEATURE_LABEL) or as DWG attributes. The default is to have them included as attributes associated with each feature. As some software packages cannot handle attributes in DWG files, you may have to switch to a different option (with the associated loss of information) to get your exported DWG files to work with some software packages. If you would like line features to have rotated labels running along the line associated with them, you have to use the option to Include Display Labels as Separate Text Layer.

The Layer Names section allows you to control how the layer names used in the exported DWG file are generated. You can choose to use the feature description, feature display label, or feature source filename as the layer name in the exported file. If you choose to use the display label as the layer name, any features that do not have a display label will use the feature description as the layer name in the exported file.

If selected, the Generate Projection (PRJ) File option causes a projection file describing the ground reference system of the DWG file to be generated in addition to the DWG file itself. The PRJ file will have the same name as the DWG file with the .prj extension.

If selected, the Create 3D Features Using Loaded Elevation Data option will cause any underlying elevation data (like DEMs) to be used to retrieve elevation values for 2D features being exported and generate new 3D features in the exported DWG file. The units used by the elevation values are determined by the Elevation Display/Export Units setting on the Vertical Options tab of the Configuration dialog.

If selected, the Generate ECEF Coordinates option will cause the exported DWG file to use Earth-Centered Earth-Fixed (ECEF) XYZ coordinate values rather than XY values in the current export projection.

If selected, the Generate Zero-Width Lines option causes and line features created in the DWG file to be marked as having zero width. Use this option if you intend to use the resulting DWG file with a product such as MicroStation which has problems with lines of non-zero thickness.

Export KML/KMZ Command

The Export KML/KMZ command allows the user to export any loaded vector data sets to a KML/KMZ format file for use with Google Earth.

When selected, the command displays the KML/KMZ Export Options dialog (pictured below) which allows the user to set up the export. The dialog consists of a KML/KMZ Options panel, a Gridding panel, and an Export Bounds panel which allows the user to set up the portion of the loaded vector data they wish to export.


The 3D Line Export, 3D Area Export, and 3D Point Export sections allow the user to control whether or not area, line, and point features with elevation values associated with them are drawn at the terrain surface or at the elevation values associated with the feature. You can specify whether the elevation values are relative to ground level or sea level if drawing the features above the terrain. If area features are drawn above the terrain, the Extrude Areas option allows you to control whether or not they will also be extruded, which means they will extend back to the terrain surface, making them look like solid 3D features. If this option is not checked, the areas will just be drawn in space as a surface and not a 3D closed object. If the Fake 2D Area Heights to Maintain Area Draw Order option is checked, exported 2D area features will be assigned fake elevation values in order to attempt to get them to layer properly when displayed in Google Earth. This is only necessary if you have overlapping areas that do not display in the correct order without this option checked. If point features are drawn above the terrain, the Extrude Points option allows you to control whether or not a thin line is drawn from the terrain surface at the location of the point to the floating symbol above the terrain surface. Enabling this option makes it easier to locate exactly where a point lies relative to the surface.

The Filled Area Translucency section allows the user to control the degree to which filled polygons are see-through in the created file.

The Feature Descriptions section allows you to setup what is contained in the description for each feature in the generated file. You can choose to include only the feature description and links to any files associated with a feature, you can choose to add attributes to this, or you can choose to provide your own HTML text to use for the feature description. If you use the HTML text option, you can embed the values of attributes from the feature in the text by enclosing the attribute name in percent signs, like %ATTR_NAME%. In addition to the name of attributes, you can also specify <Feature Name>, <Feature Desc>, <Feature Type>, <Longitude>, or <Latitude> as the attribute name to get the feature display label, description, type name, point longitude, or point latitude embedded in the result. If you need to embed an actual percent sign in your result, simply use two percent signs consecutively as an escape sequence.

The following additional options are also available:

For advanced users, you can also customize what is displayed in the balloon text that appears in Google Earth when you click on a point. You are able to customize the <Balloon Style> tag to use text with the string value stored in the registry at 'HKEY_CURRENT_USER\Software\Global Mapper\KmlExport_BalloonStyle'. If that value is empty the default setting from Google Earth will be used.

Note: Only registered users of Global Mapper are able to export data to any format.

Note: Only registered users of Global Mapper are able to export data to any format.

Export Lidar LAS Command

The Export Lidar LAS command allows the user to export any loaded 3D vector data sets (like 3D point clouds loaded from other LAS files) to new Lidar LAS format files. If the source data came from a Lidar format file, like a LAS or MrSid Lidar file, the attributes from the original data will be maintained. For other points, in addition to the base position and elevation, if there is an INTENSITY attribute available for the point, the value of that attribute will be exported as the intensity for the point in the exported LAS file. If you choose the Lidar LAS option then a compressed LASzip (LAZ) file will be created. This offers lossless compression for Lidar data that makes your Lidar files much smaller!

When selected, the command displays the Lidar LAS Export Options dialog which allows the user to setup the export. The dialog consists of a Gridding panel, and an Export Bounds panel which allows the user to set up the portion of the loaded data they wish to export.

Note: Only registered users of Global Mapper are able to export data to any format.

When selected, the command displays the LMN Export Options dialog which allows the user to set up the export. The dialog consists of a Gridding panel and an Export Bounds panel which allows the user to set up the portion of the loaded vector data they wish to export.

Note: Only registered users of Global Mapper are able to export data to any format.

Export Lowrance LCM Command

The Export Lowrance LCM (MapCreate) command allows the user to export any loaded vector data sets to a Lowrance LCM format file for use in Lowrance brand GPS devices. This allows you to create custom maps for Lowrance devices from your data. Type assignment will be done based on the built-in type assignments. In addition, the MP_TYPE attribute classification used for Polish MP exports for Garmin devices will also work for Lowrance exports, so if you provide custom classifications via the MP_TYPE attribute the type mapping should work for Lowrance exports as well.

The LCM export only has support for a limited set of types. Feature types that are not supported for LCM export will not be added to the generated LCM file, so it is important to use a built-in type (or a type with a custom MP_TYPE value that is supported) when exporting to the LCM format. The following is a basic list of the types of features that are supported:

As the Lowrance format contains some type settings that cannot be captured with just a simple Global Mapper type selection or through the assignment of a MP_TYPE attribute, you can also use a LMC_TYPE attribute to provide a specific Lowrance type to use for some types. Here is a partial list of the supported LMC_TYPE attribute values:

When selected, the command displays the Lowrance LCM Export Options dialog which allows the user to set up the export. The dialog consists of a Gridding panel and an Export Bounds panel which allows the user to set up the portion of the loaded vector data they wish to export.

Export Polish MP (cGPSMapper) Command

TUTORIAL ALERT!

Getting Started with Global Mapper and cGPSMapper - Fantastic Guide to Creating Garmin-format Maps using Global Mapper, cGPSMapper, and the other supporting applications required to get your data into a Garmin unit as a new map.


The Export Polish MP command allows the user to export any loaded vector data sets to Polish MP format files. The Polish MP format is the input format used by the cGPSMapper application which creates custom maps for Garmin GPS units.

When selected, the command displays the Polish MP Export Options dialog (pictured below) which allows the user to set up the export. The dialog consists of a Map Options panel, a Gridding panel, and an Export Bounds panel which allows the user to set up the portion of the loaded vector data they wish to export.


The Map Name and Copyright fields allow to specify the name to use for the final map when created as well as the copyright text to associate with the map.

The Map Detail section allows you to control at what zoom levels the final map will be viewable at. More detail results in a map that better represents the shape of the source data but that requires zooming further in to see the map, while less detail will result in a rougher map that shows up sooner. You should tailer this to the approximate scale of your source data, will the lowest detail setting approximating source vector data of around 1:250K scale and the highest detail setting representing 1:24K or better scale data.

Most built-in types already have a default zoom scale at which they will show up in built MP maps (this will translate to a Levels= value for the feature in the exported MP file based on the levels in the MP file header). For custom types and for types that you want to change the default zoom scale for, you can add a MP_BIT_LEVEL attribute to the feature itself or to the default attribute list for a feature type. The value of this attribute should specify the minimum MP zoom bit level that a feature should appear at. For example, if you use the maximum Map Detail setting with no template file, you will get a map with populated zoom levels at 24, 22, and 20 bits. If you wanted a feature to show up in just the lower 2 zoom levels of that map (the 24 and 22 bit resolution layers), you could add a MP_BIT_LEVEL attribute with a value of 22 to your feature or the default attribute list for that type, then that feature would get a Levels=2 value written to the exported MP file. If your map had less detail (say zoom levels of 21, 19, and 17 bits), the same feature would only show up in the most detailed 21 bit layer as features are always present in at least one layer of the map. If you want a feature to always show up at all zoom levels in your map regardless of what zoom levels are present, just add a MP_BIT_LEVEL attribute with a value of 1.

The Template File sections allows you to select a file to use as a template for the new MP file. The new file with use all of the settings from the selected template file except for the map ID (unless you check the Keep Image ID from Template MP File option) and, if you provide a map name, the map name. This includes the Dictionary setting and all levels settings. This provides a way for advanced users to set up one MP file exactly how they want and then export new maps with the same settings. You can also check the Copy Entire Contents of Template File option to have everything from the template file copied to the new file verbatim, including any feature data in the template file.

If selected, the Create as Marine Map option specifies that the created MP file will be marked as a marine map and marine features will be used if appropriate. Note that the Marine version of cGPSMapper is required to create marine maps.

The Make All Point Features Searchable controls whether or not all point features in the final map created from the MP file should be searchable on the GPS device. If the Create Transparent Map option is selected the map will be marked as transparent and any data under the map will show through.

If selected, the Save All Attributes (Even Non-MP Attributes option specifies that all attributes from exported features will be included in the exported MP file, rather than just those attributes recognized for that feature type by the MP format. Most users won't ever need to use this.

When Global Mapper exports loaded vector data to a MP file, it will automatically attempt to determine the best type to save in the MP file based on the classification of the feature in Global Mapper. If no type mapping is known, the name of the assigned Global Mapper classification will be used for the 'Type' value in the MP file. If you updated your RgnTypes.txt file in your cGPSMapper folder with the type names and the appropriate type number, you can make this work as well. You can also manually specify the type number to use for a feature by adding an attribute named MP_TYPE with the type value to use as the attribute value. If the value that you provide is for a marine type you should also provide an attribute with a name of MARINE and a value of Y. You can also override the default type mapping for built-in types by adding a default attribute list for the type on the * Styles tab of the Configuration dialog. Just add a MP_TYPE attribute to the default attribute list for a type to manually specify what type to use in exported MP files for a given Global Mapper type.

Global Mapper will automatically convert exported data to the appropriate projection and datum for export so that the Polish MP file will be correctly positioned. By default this will be lat/lon degrees with the WGS84 datum, although if you use a template file that specified a different recognized datum, Global Mapper will instead convert to that datum automatically. In any case, Global Mapper will always automatically do the right thing.

Advanced Users: If you aren't use a template to configure your export, you can customize the values used for several settings in the header for adding registry keys. The following values are supported:

Note: Only registered users of Global Mapper are able to export data to any format.

Export SEGP1 Command

The Export SEGP1 command allows the user to export any loaded 3D line and point vector data sets to a SEGP1 format file.

When selected, the command displays the SEGP1 Export Options dialog which allows the user to set up the export. The dialog consists of a Gridding panel and an Export Bounds panel which allows the user to set up the portion of the loaded vector data they wish to export.

Note: Only registered users of Global Mapper are able to export data to any format.

Export Shapefile Command

The Export Shapefile command allows the user to export any loaded vector data sets to ESRI Shapefile format files.

When selected, the command displays the Shapefile Export Options dialog (pictured below) which allows the user to set up the export. The dialog consists of a File Selection panel, a Gridding panel, and an Export Bounds panel which allows the user to set up the portion of the loaded vector data they wish to export.


The Export Areas, Export Lines, and Export Points options enable area, line, and point export respectively. Pressing the Select... button next to each of those options allows you to select the name of the SHP file to generate. In addition to the SHP file containing the actual geometry of the features, an shape index file (SHX) and attribute database file (DBF) will be created as well with the same name as the SHP file.

In general, Global Mapper will automatically determine an appropriate field type and length for any attributes exported to the DBF file created along with a Shapefile based on the values of the attribute data being exported. However, if your input data includes Shapefiles or DBF files, the original field type and length for an attribute will be used unless the attribute values being exported make that impossible.

The Split Export Based On option allows you to split up your export into separate files based on the feature type/classification, feature description, feature name, or any attribute found in the loaded data. If you choose the Split on Feature Type option, you will get the export split based on the feature classification, except in the case of the unknown types, in which case the feature description will be used automatically. The type/description/name/attribute value of the features stored in each file will be appended on to the end of the selected filenames.

If selected, the Generate Projection (PRJ) File option causes a projection file describing the ground reference system of the shapefile to be generated for each shapefile created. The PRJ files will have the same name as the SHP file with the .prj extension.

If selected, the Generate 3D Features Using Loaded Elevation Data option specifies that 3D objects should be created in the shapefile. The elevation stored for each vertex/point will be the first of the following which is available:

If selected, the Add Feature Type (LAYER) Attribute to DBF option specifies that the type description for each exported feature will be added as a LAYER attribute to the DBF file generated with the SHP file.

If selected, the Add Style Attributes to DBF option specifies that style attributes should be added to the generated DBF file containing information about the drawing style and label font used for each feature. If you check this then when you reload your data in Global Mapper (but typically not other applications) it should maintain its drawing style

If selected, the Generate Multi-Patch Features for Areas option specifies that multi-patch features should be generated for area exports rather than normal polygon records. This is useful for exporting 3D models, such as those you would load from Google SketchUp SKP files.

WARNING: The Shapefile format uses a DBF file for attribute storage, which means that any attribute names are limited to 10 characters. Any attribute names longer than that will be truncated with a number potentially added on to maintain uniqueness among multiple long attribute names.

Note: Only registered users of Global Mapper are able to export data to any format.

Export Simple ASCII Text File Command

The Export Simple ASCII Text File command allows the user to export any loaded vector data sets (i.e. areas, lines, and points) to a delimited ASCII text file. Each vertex in an area or line and the position of each point will be represented.

When selected, the command displays the ASCII Export Options dialog which allows the user to setup the export. The dialog consists of an Options panel (pictured below) and an Export Bounds panel which allows the user to set up the portion of the loaded data they wish to export.


The Options panel allows the user to specify what character to user to separate the x, y, and z coordinates of each vertex. In addition, the user can specify that they wish to separate each vector feature with a blank line or some other custom separator text. The Coordinate Order section allows the user to control the order in which the X (easting/longitude) and Y (northing/latitude) coordinates are exported. The export of elevation data is controlled with the Export Elevations option. The Include Feature Attributes Before Coordinate Data and Include Drawing Style Attributes Before Coordinate Data options respectively control whether or not feature attributes or feature drawing style information is saved to the file on the lines preceding the coordinate data for a feature.

If elevations are being exported, Global Mapper first looks for an elevation associated with the vertex being exported. If no elevation is associated with the vertex, Global Mapper then checks all loaded elevation grid data in reverse order of display to see if any of them have an elevation at the vertex location. If so, that elevation is used.

ADVANCED USERS - In Global Mapper v11.02 and later you can customize the number of decimal digits written out for the X and Y coordinates for a Simple ASCII Text export through the use of a DWORD registry key 'HKEY_CURRENT_USER\Software\Global Mapper\ASCIIExportCoordPrecision'. For example, set this value to 6 to get 6 decimal digits for each X, Y, and Z coordinate.

Note: Only registered users of Global Mapper are able to export data to any format.

Note: Only registered users of Global Mapper are able to export data to any format.

Export WAsP MAP File Command

The Export WAsP MAP File command allows the user to export loaded line and area features to a WAsP MAP format file for use with the WAsP (Wind Analysis and Application Program) application (http://www.wasp.dk/.

Only those line features with an elevation and/or valid roughness attributes will be exported. Only those area features with valid roughness attributes will be exported. Valid roughness attributes consist of a ROUGH_L and a ROUGH_R attribute containing numeric values for the left and right roughness for the feature. If neither of those attributes exist but a RV, ROUGHNESS, or ROUGH attribute is available, that value will be used for both the left and right roughness for that feature.

When selected, the command displays the WAsP MAP Export Options dialog which allows the user to setup the export. The dialog consists of an Export Bounds panel which allows the user to set up the portion of the loaded data they wish to export.

Note: Only registered users of Global Mapper are able to export data to any format.

Batch Convert/Reproject

The Batch Convert/Reproject command allows the user to easily convert multiple files in one format to another format.

When the command is selected, the user is first prompted to select the file type to convert from using the dialog pictured below. Once an input file type is selected, another dialog with a list of all compatible export file types is displayed, allowing the user to select what type of file to convert the input files to. Finally, after the input and output file types are selected, the Batch Convert dialog (pictured below) is displayed, allowing the user to set up the batch conversion.




The Source Files section displays the list of source files currently selected to be converted. Pressing the Add Files... button allows the user to select additional files for conversion. Pressing the Add Directory... allows the user to easily add an entire directory's worth of source files to the to-be-converted list. All directories under the added one can be recursively searched if so desired by answering Yes to the dialog that pops up immediately after selecting the directory. Pressing the Add Loaded Files button causes all files loaded into the main Global Mapper view that match that batch convert input type to be added to the list of files to be converted. Pressing the Add Onscreen Files button causes all files loaded into the main Global Mapper view that are currently at least partially onscreen and that match the batch convert input type to be added to the list of files to be converted.

The Directory section allows the user to choose where they would like the newly created output files to be created. The Use same directory as file being converted option causes the output file created off of each source file to be created in the same directory as the source file. The Specify output directory option allows the user to choose a specific directory to output all of the newly created output files to.

The File Names section allows the user to choose whether the newly created output files should have the same file name as the source file they were created from (Use Source File Name option) or whether the more readable quadrangle name (if available) or layer descripiton should be used as the file name for the newly created output file (Use Quad Name or Description option). If the Use Source File Name option is selected, you can also specify an additional text string to append to each new filename to identify it.

The Projection section allows the user to choose whether or not each newly created output file should either use the same projection as the file that it was created from (Use Source File Projection option) or if each file should use a projection specified by pressing the Projection button. If the user selects to specify an output projection and they select a zoned projection like UTM or Gauss Krueger, they will have the option on the projection selection dialog to have the best zone for the center of the output map automatically used if they select the Automatically Select Best Zone option in the Zone box on the projection selection dialog.

The Setup Gridding (i.e. Tiling) button displays a dialog allowing the user to specify if and how to break up each file being converted into multiple new files. This option is only available when converting to a raster or gridded elevation format.

The Setup Sample Spacing button displays a dialog allowing the user to choose to either keep the sample spacing of source raster and elevation files when converting the selected or to specify a new sample spacing to resample all of the selected input files at when performing the conversion. This option is only available when converting to a raster or gridded elevation format.

The Horz Datum selection allows the user to choose the horizontal datum that each newly created output file should use. By default, each output file will use the same horizontal datum as the source file that it was created off of. Alternately, the user can specify to have all output files created in NAD27, NAD83, WGS72, or WGS84 with the appropriate offset being applied automatically.

The Vertical Units selection is present only for some conversions and controls the output elevation units.

The Palette selection is present only for some conversions and controls the palette, if any, used in the output files. The palette values are defined as follows:

The additional list of options varies depending on the particular conversion being performed. The meaning of those options is defined below:

You can also right click on the list of files to convert and choose to save that list of files to a text file. This can be a convenient way to start a Global Mapper script to do other processing on the files. Other right-click options include the ability to remove all archive files, like .zip and .tar.gz from the list and to fill the source files list with files listed in a text file.

Note: Only registered users of Global Mapper are able to perform batch conversions.

Combine Terrain Layers Command

The Combine Terrain Layers command allows the user to generate a new gridded elevation (or other gridded value) layer by combining and/or comparing the elevation values from two other loaded terrain layers.

When selected, the command displays the Combine Terrain Options dialog which allows the user to set up generation of the new terrain layer. Once completed the new terrain layer is added to the Overlay Control Center and displayed.


The Combine Terrain Layers Options panel (displayed above) allows the user to select the name to assign to the newly generated layer, select the layers to combine to make the new layer, select the operation to perform when combining the new layer, and select the vertical units and sample spacing of the new layer. The available operations are described below:

Note: Only registered users of Global Mapper are able to combine terrain layers.

Generate Contours Command

The Generate Contours command allows the user to generate equally spaced contour lines from any loaded elevation grid data.

When selected, the command displays the Contour Generation Options dialog (pictured below) which allows the user to set up the contour generation process.


The Contour Options panel (displayed above) allows the user to set the contour interval and units as well as the grid spacing to use when generating the contours. You can also restrict the elevation range within which contour lines are generated (by default all loaded elevation values are considered). In addition, options are available to generate isoheight area features in addition to contour lines as well as spot elevations at the highest and lowest points in the area over which the contours are generated. The smoothing option controls whether or not extra vertices are added along generated line and area features to improve their appearance. If you need to generate a huge amount of contour lines over a large area, the option to export the contours directly to a package file can be used in addition to the Gridding tab options to export those contours directly to package files to get around memory limitations. Note that the contour lines will be generated so that the higher elevations are to the left of the contour line.

The ADVANCED: Create Contours Where Elevations Pass Down to Contour Value Rather Than as They Go Down From One option is an advanced option allowing you to change how the contouring works in flat areas. If this option is checked, you will get contours generated where the terrain surface arrives at a contour height from higher terrain rather than where it departs a contour height for lower terrain. So if you have a flat plain exactly at a contour height you will get the contour at the base of the hill where it starts up rather than at the top where it starts down. This is most useful when you have water (like the ocean) and want to get a shoreline contour generated where the terrain leaves the flat surface of the water.

The Simplification panel (displayed below) allows the user to set up the threshold at which points that don't contribute much to the shape of the generated contour are removed in order to generate lines with less vertices. The Gridding panel allows you to break up your contour generation into smaller pieces which can sometimes help reduce memory requirements when generating a very large amount of contour lines. The Export Bounds panel allows the user to set up the portion of the loaded elevation grid data they wish to consider when generating the contours.




Generate Watershed Command

The Generate Watershed command allows the user to perform a watershed analysis on loaded terrain data to find stream paths as well as delineate the watershed areas that drain into a given stream section. The watershed calculation uses the eight-direction pour point algorithm (D-8) to calculate the flow direction at each location, along with a bottom-up approach for determining flow direction through flat areas and a custom algorithm for automatically filling depressions in the terrain data.

When selected, the command displays the Watershed Generation Options dialog (pictured below) which allows the user to set up the watershed generation process.


The Resolution section controls the resolution at which the loaded terrain data is sampled to perform the watershed analysis. The default values should capture the full resolution of the loaded terrain data. Larger values (i.e. lower resolution) will cause the calculation to be quicker, but less detailed.

The Stream Threshold section controls how much water must flow to a particular cell before it is considered part of a "stream". Larger values will result in only more water flow areas being delineated, while smaller values will cause more minor water flows to be marked as streams. Each stream segment (i.e. the portion between and inflow and outflow point) can optionally have the area that drains directly to that stream segment marked with a watershed area. Check the Create Watershed Areas Showing Drainage to Streams option to enable creating watershed areas.

Many terrain data sets will contain depressions in the data where flow would terminate unless allowed to fill the depression and spill into the surrounding terrain. The Depression Fill Depth section controls how deep of a depression will be filled before it is considered a basin and flow is allowed to terminate there. The depression fill depth value will automatically be filled in with some guess at a good value based on the range of loaded elevation values, but you might want to modify this, especially if you have relatively flat terrain with a lot of depressions. Note that it can take a while to fill particularly deep depressions. When trying to determine a a good value to use for the depression fill depth you should think about how high of an embankment or 'dam' that you might encounter that you want to allow water to fill up to the top of and pour over, or also how deep of a small pond or puddle to fill and allow spilling out of. You can also check the option to Save DEM to Global Mapper Grid File After Filling Depressions to save the depression-filled terrain to a GMG file so you can load that for future watershed operations to avoid having to fill depressions again.

The Operations at Selected Point Locations section allows you to perform additional flow and drainage network delineation based on point locations selected in the Digitizer Tool. The Create Watershed Areas Showing Drainage to Selected Point(s) option will calculate a drainage (watershed) area for each selected point features showing which portion of the loaded terrain drains to the immediate vicinity (i.e. within one sample of the point location) of the selected point. The Trace Flow from Selected Point(s) (Water Drop Analysis) option will cause a separate arrowed line to be generated starting at each selected point feature showing where a drop of water placed at that point location will flow to.

The screenshot below shows a watershed created from a collection of USGS DEMs. In it you can clearly see the stream network as well as the drainage areas for each stream segment.




Print Command

The Print command allows the user to print the contents of the current view window. When selected the Print dialog (picture below) is displayed, which allows the user to set up the print process.


The Header field allows the user to specify text to be displayed above the printed map image. This text will be printed centered above the map image on the printout.

The Footer field allows the user to specify text to be displayed below the printed map image. This text will be printed centered below the map image on the printout. The footer text will default to the text displayed on the status bar for the active tool, such as the measurement information for the current measurement in the Measure Tool.

Selecting the Print in Black and White option causes the printout to be generated in black and white, rather than full color even when printing to a color printer. The generated image will be a 256-level grayscale image.

Selecting the Use White Background Color option causes any background areas being printed to be filled with white so as not to use any printer ink. Uncheck this option is you want the currently configured background color to be maintained on the printout.

The Extra Margin Around Printout setting allows you to specify an extra margin to draw around the output. This is useful when printing to things like a PDF file that do not have any natural margins like a printer does.

The Print To Scale option allows you to specify that you want the printed result to match a certain scale, like 1:1000. This means that one inch on the printed paper will correspond to 1000 inches in the real world. If you choose to print to a certain scale, the printout will be centered on the center of your current screen view, but the appropriate amount of information will be rendered to achieve the requested scale.

The Print To File section allows you to specify that the printout be directed to an image file rather than to the printer. This can be handy if you either want to save the results of the printout to email to someone or post on a web site, or you are having trouble printing and would like to print out the data generated by Global Mapper using another application.

The Print Bounds panel allows the user to select exactly what area to print (the default is the current screen contents). This panel behaves just like the Export Bounds panel found on most export dialogs.

Print Preview Command

The Print Preview command allows the user to preview what a printout of the contents of the current view window would look like.

Print Setup Command

The Print Setup command allows the user to setup their printer for printing the current view window.

Exit Command

The Exit command closes the Global Mapper application.

View Menu

The View menu offers the following commands:

Toolbars

Use this command to display and hide the Toolbars, which includes buttons for some of the most common commands in Global Mapper. A check mark appears next to the menu item when the Toolbar is displayed



Status Bar


The status bar is displayed at the bottom of the Global Mapper window. To display or hide the status bar, use the Status Bar command in the View menu.

The left area of the status bar describes actions of menu items and toolbar icons. The left area of the status bar will also show color or elevation of the current pixel if it's over a raster image, or the description of the closest vector overlay component. If the nearest line feature to the cursor contains recognized addressing information, the address nearest the cursor will be displayed.

The right areas of the status bar indicate the current view scale and the current mouse position in both the global ground reference system and in the Position Display Format currently selected from the Configuration dialog.

Background

The Background command brings up a color dialog box from which the user can select a color to be the new background color of your Global Mapper window. The background color selected will also be used to fill in areas of no data in exported raster imagery (i.e. GeoTIFF and JPG files).

Center on Location

The Center on Location command allows the user to manually enter a location to recenter the view on, providing a quick and easy way to center yourself on a particular location.

Properties Properties

The Properties command displays a dialog listing properties about the current view window.

Full View

The Full View command zooms such that all of the currently loaded overlays fit in the view window. This command also places the overlays in the center of the view window.

Zoom In

The Zoom In command zooms the current view in by a factor of 2.

Zoom In Micro

The Zoom In Micro command zooms the current view in by a small amount.

Zoom Out

The Zoom Out command zooms the current view out by a factor of 2.

Zoom Out Micro

The Zoom Out Micro command zooms the current view out by a small amount.

Zoom To Scale

The Zoom To Scale command zoom the current view to a user-specified scale. For example, to make one inch on the screen be equivalent to 1 mile of ground truth, you would enter a scale of 63360 (this is the number of inches in a mile).

Zoom To Spacing (Pixel Size)

The Zoom To Spacing command zoom the current view so that each pixel on the screen represents a user-specified number of ground units.

Save Current View

The Save Current View command saves the current map view bounds. The saved view can later be restored by using the Restore Last Saved View command. This feature allows you to save a view at one spot, then pan and zoom around and load additional data, then restore your view to the saved spot in one simple operation.

Restore Last Saved View

The Restore Last Saved View command restore the map view to the location last saved using the Save Current View command.

Restore Last Drawn View

The Restore Last Drawn View command restore the map view to the view that was last drawn on the main map. You can use this to back up threw recently drawn view locations and zoom levels.

Name and Save Current View

The Name and Save Current View command associates the current map view bounds with a user-specified name. The saved view can later be restored from a list of named views using the Restore Named View command. This feature allows you to save multiple views with descriptive names, then easily restore those views at a later time.

Restore Named View

The Restore Named View command allows you to restore a previously saved map view. You can save map views for later restoration using the Name and Save Current View command.

Search Menu

The Search menu currently provides the following commands:

Search By Name

The Search By Name command allows for searching for features in all loaded vector data by name. When selected, the Find By Name dialog is displayed.


The Find By Name dialog displays a list of all of the vector features (areas,lines, and/or points) whose label starts with the search string specified in the Search String field. This field can contain the ? and * wildcard characters. In addition, one can control which vector object types (area,line, and/or point) to include in the search. Double-clicking on an item in the list will recenter the view on that object and show a bullseye on it (hold down the ALT key when double-clicking to not show the bullseye).

The Edit Selected button displays a dialog allowing the user to modify the name, feature type, and drawing style of any features selected.

The Delete Selected button will mark all selected features as deleted.

This dialog is particulary handy with the GNIS (Geographic Names) database which is freely available for download.

Search By Attributes, Name, and Description

The Search By Attributes, Name, and Description command allows for searching for features in all loaded vector data by attribute value, name, feature index within the layer, and description/type. When selected, the Search Vector Data dialog is displayed.


The Search Vector Data dialog displays a list of all of the vector features (areas, lines, and/or points) which match the specified Search Criteria. The Search Criteria can be applied to any attribute value of the loaded features, the display label field, or the description/type field. Comparisons to the Compare Value can be done either textually or numerically. For text equal and not-equal searches, the Compare Value field can contain the ? and * wildcard characters.

In addition, one can control which vector object types (area, line, and/or point) to include in the search and also whether to limit the search to those features that are on-screen.

Once you have your Search Criteria set how you want for the search, press the New Search button to actually perform the search and display the matching results in the results list. The results will be sorted in ascending order by the names of the features by default, but you can click on any column header to sort the results by the values in that column. Clicking the same column header again will reverse the order of the sort. You can also press the Search in Existing Results button to apply the new search criteria to the existing results. Using this you can create complicated searches based on multiple criteria.

Double-clicking on an item in the list will recenter the view on that object.

The Edit Selected button displays a dialog allowing the user to modify the name, feature type, and drawing style of any features selected.

The Delete Selected button will mark all selected features as deleted.

If you right click on the results list, additonal options will appear, such as the option to select all of the results in the list. If multiple line features are selected in the results list, when you right click there will be an option to combine those line features into new line features if the selected lines connect at their endpoints. Options for copying the selected features to the clipboard and selecting the selected search results with the Digitizer Tool for further editing will also appear if any results are selected.

ADVANCED USERS: You can change the default search string from '*' to whatever you want by creating a new registry string value with the desired default search string at "HKEY_CURRENT_USER\Software\Global Mapper\DefaultVectorSearchStr".

Search and Replace

The Search and Replace command allows for searching for a particular text string in the attributes and name of loaded features and replacing that with some other text string. When you select the command, the Search and Replace dialog (pictured below) is displayed, allowing you to setup the search-and-replace operation.


When searching, you can either enter a Search Text value of the string to match on, or you can enter an asterisk (*) to match any non-empty value. You can also use the asterisk (*) at the start or end of the search string to look for text that starts or ends with some particular text.

In the Replace Text box you have more options. You can specify a simple text string to replace the Search Text with, or you can use a single wildcard to prepend or append text.

For example, to prepend the text 'Sample' in front of your search string, enter a replace string of 'Sample*'. To append the text to your search string, use '*Sample'. If you want to replace any string that starts with the sequent 'N ' with 'North ', use a search string of 'N *' and a replace string of 'North *'.

Find Address

The Find Address command displays the Search for an Address in the US dialog (pictured below) which allows searching for an address, city, or zip code in the United States.


If an address is found that matches the requested location, a results dialog (see sample below) is displayed with the matching location information, as well as button to allow creating a new point feature at the address location, re-centering the map view on the address, and copying the address information to the Windows clipboard for easy pasting into another application.


The dialog also includes a Geocode Addresses from File button that allows you to geocode a bunch of addresses at once. The text file that you select to convert can either contain a list of files with addresses in the single line form accepted when searching on a single address, or it can be a comma or tab-delimited file with named columns, like Address, City, State, and Zip (see the example file contents below). Note that you are limited to about 5,000 address searches within a single 24 hour period.

Sequence,Name,Address,City,State,ZIP,Phone
1,McPeak Betty,,North Pole,AK,99705,907-488-4879

9,McPeak Faye,395 Dupree Dr,Huntsville,AL,35806,256-837-2657

When batch geo-coding, you can choose to either geocode US addresses against an online database, or to geocode to loaded road data instead. If you choose to geocode against loaded road data, you must already have road data loaded with a known address format, like Tiger/Line data in the US, or data with supported attribute names for addressing information, like R_FROM_ADR, L_TO_ADR, R_FROM_CITY, L_TO_CITY, etc., so that the data can be geocoded.

Once you complete a batch geocode operation, the results are displayed in a list in a dialog (see sample below). The Batch Geocode Results dialog contains buttons allowing you to create new point features from the matched address results or to export the results to a new file.



Find Features with Duplicate Attribute Values

The Find Features with Duplicate Attribute Values command allows you to search loaded vector features to find those that have duplicate values for a selected attribute value. You can then view the results and manually edit them, or choose to automatically assign unique numeric values for the selected attribute so that duplicates no longer exist.

When you select the menu item you are first prompted to select which attribute (including feature name) to search for duplicates on, then the search proceeds and any duplicate values are display in the Duplicate Search Results dialog (picture below). This dialog allow you to view the features with duplicate results and to edit those features or automatically assign new unique values. You can also press the Delete Duplicates button to mark the duplicate features as deleted. When doing this you will have the option to mark all duplicates (except for the first one) as deleted, or to just delete the duplicate features that also have duplicate coordinates (this is what you'll most often want to do).
