FAQ
MRF to CG4 Conversion
What are MRF files?
MRF (Meta Raster Format) is a format for very large images, such as global satellite mosaics, that was developed at NASA's Jet Propulsion Laboratory to serve maps to web browsers quickly. The picture is divided into many small square tiles, and the tiles are stored at several levels of detail, from the whole image at full resolution down to small overviews. A viewer needs to load only the few tiles that are visible, which makes it practical to browse images of enormous size. An MRF dataset is made of three files: a small readable file with the .mrf extension that describes the image, a data file with the tiles, and an index file with the .idx extension that tells where each tile is. NASA uses the format for its Global Imagery Browse Services, and Esri has helped to develop it further.
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.
