FAQ
MRF to PGM 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 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.
