- Description
- FTS file format is used to edit, store and transmit images with metadata (data with spatial and photometric calibrations) for scientific purposes. Most times it stores the data without the actual associated 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.
