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.

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.

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:

• Point Only - All lines from the file which are determined to contain coordinate data will result in a single point feature to be generated.
• Point, Line, and Area Features - Any string of two or more consecutive lines with coordinate data will result in a line or area feature. All isolated coordinate lines will result in a point feature.
• Elevation Grid - All lines from the file which are determined to contain 3D coordinate data will be use generated a triangulated terrain which is then gridded to create a elevation grid. This grid has all the capabilities of an imported DEM, including contour generation, line of sight and view shed analysis, and raster draping. When selecting this option, the Create Elevation Grid dialog will appear after setting up the ASCII file import options to allow setting up the gridding process.

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 Columns to Skip at Start of Line setting controls what 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 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 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):

• NAME or LABEL - the value associated with an attribute of either of these names will be used as the feature name.
• DESC, DESCRIPTION, LAYER, or TYPE - the value associated with an attribute of any of these names will be used as the feature description.
• GM_TYPE - the value associated with an attribute with this name or any of the description names listed above will be used to attempt to assign a classification other than the default for each feature. The value must match one of the classification names in Global Mapper to work. It will also work for user-created custom types.
• ELEVATION, HEIGHT, or DEPTH - the value associated with an attribute of any of these names will be used as the feature's elevation.
• SYMBOL, POINT SYMBOL, or POINT_SYMBOL - the values associated with an attribute of any of these names will be compared against the names of the symbols available in Global Mapper (including any custom symbols). If a match is found, that symbol will be used for the point feature. These attribute names are ignored for line features. You can also specify custom dot and square symbol colors and sizes without having to add your own custom bitmaps for those symbols. Use names of the form DOT_CUSTOM_[SIZE]_[RED]_[GREEN]_[BLUE] and SQUARE_CUSTOM_[SIZE]_[RED]_[GREEN]_[BLUE] where the [SIZE] value is the radius in pixels of the dot or square, and the [RED], [GREEN], and [BLUE] values represent the color to use. For example, to specify a dot symbol of radius 10 pixels with a color or green, you would use a symbol name of DOT_CUSTOM_10_0_255_0.
• COLOR - the COLOR attribute should be formatted as RGB(red,green,blue). In the absence of a specific fill or line color, it will be used.
• LINE COLOR, LINE_COLOR, BORDER COLOR, BORDER_COLOR, PEN COLOR, or PEN_COLOR - the values associated with an attribute of any of these names will be used as the color for the pen used to draw line features. The values must be formatted according to the guidelines layed out for the COLOR attribute in order to be recognized.
• LINE WIDTH, LINE_WIDTH, BORDER WIDTH, BORDER_WIDTH, PEN WIDTH, or PEN_WIDTH - the values associated with an attribute of any of these names will be used as the width for the pen used to draw line features.
• LINE STYLE, LINE_STYLE, BORDER STYLE, BORDER_STYLE, PEN STYLE, or PEN_STYLE - the values associated with an attribute of any of these names will be used as the style for the pen used to draw line features. Valid values are Solid, Dash, Dot, Dash - Dot, Dash - Dot - Dot, and Null. Only the Solid value is valid for lines with a width greater than 1
• LABEL_ON_LINE - if this is set to "YES" or "TRUE", the label (if any) for this line feature should be rendered centered on the line
• CLOSED - if this is set to "YES" or "TRUE", the feature will be treated as a closed area feature if it has at least three vertices.
• ISLAND - if this is set to "YES" or "TRUE", the feature will be treated as an island of the previous closed parent area feature if it has at least three vertices. If there are no previous parent areas, this attribute will be ignored.
• FONT_NAME - specifies the name (e.g. Arial, Times New Roman, etc.) of the font to use when displaying the display label, if any, for this feature.
• FONT_COLOR - specifies the color of the font to use when displaying the display label, if any, for this feature. The values must be formatted according to the guidelines layed out for the COLOR attribute in order to be recognized.
• FONT_ANGLE - specifies the angle in degrees of the font to use when displaying the display label, if any, for this point feature.
• FONT_SIZE - specifies the point size of the font to use when displaying the display label, if any, for this feature.
• FONT_HEIGHT_METERS - specifies the height in meters of the font to use when displaying the display label, if any, for this feature. Using this causes the actual point size of the font to vary as you zoom in and out.
• FONT_CHARSET - specifies the numeric character set of the font to use when displaying the display label, if any, for this feature. These correspond to the Windows character set enumeration.

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 Digital Globe, GlobeXplorer, and AirPhotoUSA, as well as seamless USGS topographic maps and satellite imagery for the entire United States, as well as high resolution color aerial imagery for select metropolitan areas from 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 and color satellite imagery 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 Digital Globe 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 WMS Data Source button to display the Select WMS Data Source to Load dialog (pictured below). This dialog allows you to specify the URL of a WMS 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 (a great source of data, like Blue Marble imagery). 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'.

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.

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.

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.

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 and control at what zoom level data layers are loaded for display.

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.

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.

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.

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:

• JPEG - JPEG is a lossy format that achieves excellent compression on images with a lot of color variation, such as pictures of real world objects and shaded elevation data.
• PNG (Portable Network Graphic) - PNG is a lossless format that achieves excellent compression on images without a lot of color variation, such as line (vector) drawings and paper map scans such as DRGs. The generated PNG file will be of the 24-bit variety.
• (Geo)TIFF - TIFF is a lossless format that is supported by many GIS packages. Saving the screen to a TIFF with this command generated a 24-bit uncompressed TIFF. In addition, all georeferencing data is stored in a GeoTIFF header attached to the TIFF, making the image completely self-describing.
• Windows Bitmap (BMP) - BMP is a widely support format on Windows platforms. Saving the screen to a BMP results in a 24-bit uncompressed image.

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.

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.

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 TerraServer data, and other options.

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

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 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.

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.

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.

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.

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.

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.

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

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.

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.

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.

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.

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

When selected, the command displays the Erdas Imagine Export Options dialog which allows the user to setup the export.

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

When selected, the command displays the Float/Grid 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.

When selected, the command displays the Geosoft 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 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.

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:

• 8-bit Palette Image - This option generates a 256-color raster GeoTIFF file with 8-bits per pixel. The Palette options described below will apply in this case. This option will generate a relatively small output file, at the expense of some color fidelity depending on the palette that you choose. The image data will be compressed using the PackBits compression algorithm.
• 24-bit RGB - This option generates a raster GeoTIFF file with 24-bits per pixel. GeoTIFF images generated with this option will be at least 3 times the size of those generated with the 8-bit Palette option, but the colors in the image will exactly match what you see on the screen.
• JPEG-in-TIFF - This option generates a raster GeoTIFF file with 24-bits per pixel but with the raster data compressed using the JPG compression algorithm. GeoTIFF images generated with this option will maintain good color fidelity and often be highly compressed, although they will lose some information as compared to the uncompressed 24-bit RGB option. Something else to keep in mind if selecting this option is that many software packages do not yet support GeoTIFF files that use the JPEG-in-TIFF compression option. By default the JPG compression used in the GeoTIFF file uses a quality setting of 75, but you can modify this by creating a new DWORD registry key with the desired value at "HKEY_CURRENT_USER\Software\Global Mapper\JpegInTiffQuality".
• Black and White- This option generates a two color GeoTIFF file with 1 bit per pixel. This will generate by far the smallest image, but if you source image had more than two colors the resulting image will be very poor. By default, white will be a value of 0 and black will be a value of 1, but you can reverse this by selecint the Grayscale - Min Is Black palette option.
• Elevation (16-bit integer samples) - This option generates an elevation GeoTIFF using the currently loaded elevation grid data sets. Elevation samples will be stored as signed 16-bit integers. There are only a handful of software packages that can recognize a vertical GeoTIFF properly, so only use this if you know it works.
• Elevation (32-bit floating pointr samples) - This option generates an elevation GeoTIFF using the currently loaded elevation grid data sets. Elevation samples will be stored as 32-bit floating point values. There are only a handful of software packages that can recognize a vertical GeoTIFF properly, so only use this if you know it works.

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:

• Image Optimized Palette - The palette generated will be an optimal mix of up to 256 colors that will closely represent the full blend of colors in the source images. This option will generate the best results, but can more than double the export time required if any high color images are present in the export set. If all of the input data is palette-based and the combined palette of those files has 256 colors or less, then the combined files of the input file will just be used with no additional export time being required.
• Grayscale Palette - This palette consists of 256 scales of gray ranging from black to white.
• DRG Optimized Palette - This palette is optimized for the exporting USGS DRG data. The palette consists of only the standard DRG colors.
• DRG/DOQ Optimized Palette - As the name suggests, this palette is optimized for exporting a mixture of USGS DRG data and grayscale satellite photos (i.e. USGS DOQs). The palette consists of the 14 standard DRG colors with the remaining 242 colors being a range of gray values ranging from black to white.
• Halftone Palette - The palette consists of a blend of 256 colors evenly covering the color spectrum. This palette is the best choice when exporting anything but DRGs and grayscale satellite photos.
• Custom Palette from File - This option allows the user to choose a .pal file describing the palette to use for the export. A .pal file should be a text file with one line per color, with the red, green, and blue color components for each color in the palette separated by a comma. You can save a .pal file for an existing palette-based file by opening the Overlay Control Center, selecting the palette-based layer, press Options, then the Transparent Color button, then selecting the option to save a color palette file.
• Grayscale - Min is Black Palette - This palette creates an 8-bit per pixel grayscale image with no color map stored in the image. Black will be stored as zero with varying shades of gray up to white with a value of 255.
• Grayscale - Min is White Palette - This palette creates an 8-bit per pixel grayscale image with no color map stored in the image. White will be stored as zero with varying shades of gray up to black with a value of 255.

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.

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.

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 Use LZW Compression option is checked, the image data will be compressed using the LZW compression algorithm. This generally results in the best compression for TIFF files, but is not yet supported by all software applications. If the application(s) that you are going to be using the TIFF file with supports LZW, using this compression method is definitely suggested.

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

If the Make Background (Void) Pixels Transparent option is checked for 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.

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.

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.

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.

The 3D Line Export and 3D Area Export sections allow the user to control whether or not area and line 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.

The Filled Area Translucency section allows the user to control the degree to which filled polygons are see-through in the created file. If the Create Compressed KMZ File option is checked, a compressed KMZ file will automatically be created. This will result in much smaller files and is highly recommended unless you plan on manually editing the export result yourself in a text editor. If the Include Attribute Values in Feature Description option is checked, any feature attributes will be included in the description for a feature. If the Hide Point Features by Default When Loading File option is checked, all of the point features exported to the file will be hidden by default in Google Earth so as not to clutter up the display with a bunch of point icons. If the Display Area and Line Labels option is checked, each exported line or area feature with a display label will also be marked with a clickable placemark displaying the label for that area or line feature. This is the only way to get line or area features to display labels in Google Earth.

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.

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.

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

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.

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:

• The elevation associated with the vertex/point in question.
• The elevation associated with the entire feature being exported. For example, the elevation of a contour line.
• The first elevation obtained by searching the loaded elevation grid layers at the position of the vertex/point.
• A value of 0.0 will be used if no elevation could be obtained via any of the prior methods.

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 Split Into Separate Files by Feature Layer/Description option specifies that the export will be split into separate files based on the description for each feature. The description of the features stored in each file will be appended on to the end of the selected filenames.

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

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.

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

The Export Surfer BLN command allows the user to export any loaded vector data sets to a Surfer BLN format file used by Golden Software's Surfer package to specify breaklines.

When selected, the command displays the Surfer BLN Export Options dialog which allows the user to set up the export. The dialog consists of 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.

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