FAQ
CUB to QOI 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 QOI files?
QOIQOI (Quite OK Image) is a fast, lossless image format designed as a simpler alternative to PNG. It offers similar compression quality but with much faster encoding/decoding speeds, making it ideal for applications where performance matters.
