CUB to PGM Conversion
What are CUB files?
CUB is the cube file format of the Integrated Software for Imagers and Spectrometers (ISIS), developed by the USGS Astrogeology Science Center to process planetary imagery and spectral data returned by space missions. A file of this type stores a three-dimensional array of pixels defined by samples, lines, and bands, together with a text label written in Planetary Data System Version 3 (PDS3) keyword syntax. The label describes the dimensions, pixel type, byte order, target body, map projection, and instrument and acquisition details, and may be followed by additional objects such as history records, camera geometry tables, and polygon footprints. The label can be attached at the beginning of the file or stored in a separate file. The format is used for mosaics, map-projected images, and elevation models of the Moon, Mars, and other solar system bodies.
What are PGM files?
The PGM or Portable Graymap format is part of a package of open source graphics programs called Netpbm. Other Netpbm formats include PPM (Portable Pixmap) and PBM (Portable Bitmap), also known under the collective name of PNM (Portable Anymap). A PGM file includes a grayscale image, can work on a UNIX platform, as well as on Windows or Mac OS X, and can render a scope of up to 255 grayscale colors.
