Meta Raster Format (MRF) is an image and data storage format designed for fast access to imagery within a georeferenced tile pyramid at discrete resolutions. It was originally developed at NASA's Jet Propulsion Laboratory.

[edit] Format details
It is a composite format, with an image consisting of 3 components:
- MRF metadata file in XML format (file extension: .mrf)
- MRF data file. This can be a "Pile of PNGs" (file extension: .ppg) or a "Pile of JPEGS" (file extension: .pjg), in which case the data file contains blocks of concatenated images in PNG or JPEG format. Other possible formats include LERC.
- MRF index file (file extension: .idx)
