FAQ
CUB to CG4 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 CG4 files?
CG4 is a raster format associated with CALS (Continuous Acquisition and Life-Cycle Support) — a program initiated by the US Department of Defense to capture and link military data. CG4 is compatible with a very limited number of digital graphics programs. Files with this extension contain a bitmap that often uses the CCITT4 compression, which is an old fax machine standard used for black-and-white images.
