Supports compression: Wavelet (lossy)
Supports color map: No
Introduction
MrSID was originally developed for Geographic Information Systems (GIS). With this format, large raster image files such as aerial photographs or satellite imagery are compressed and can be quickly viewed without having to decompress the entire file.
