BIL/BSQ/BIP/RAW Imagery

Description:
Various types of imagery are often distributed in simple binary formats such as the BIL (binary interleaved), BSQ (binary sequential), BIP (binary interleaved pixel), and RAW (PCI Geomatics raw binary) formats. These files are usually accompanied by a header file of some kind (usually .hdr, .ers, or .aux) which describes the layout and formatting of the file. Global Mapper requires this header file in addition to the .bil, .bsq, .bip, or .raw data file in order to load the file.

PGM Grayscale Grid Format

Description:
A PGM image represents a grayscale graphic image. There are many psueudo-PGM formats in use where everything is as specified herein except for the meaning of individual pixel values.
