Description
Image created using Multi-resolution Seamless Image Database (MrSID) compression, which was developed by Extensis for compressing large images; commonly used to partition and store large Geographic Information Systems (GIS) images.
A PGM file is a grayscale image file saved in the portable gray map (PGM) format and encoded with one or two bytes (8 or 16 bits) per pixel. It contains header information and a grid of numbers that represent different shades of gray from black (0) to white (up to 65,536). PGM files are typically stored in ASCII text format, but also have a binary representation.
