MrSID files
MrSID is a proprietary compressed image file format of [LizardTech] It has become very popular for GIS files, especially orthophotos because it is efficient and lossless.
It is proprietary so it's not supported in GRASS.
But all is not lost! The kindly folk at LizardTech supply a free decoder. It is available for Windows, Linux and Solaris. It will convert MrSID images to JPG, GeoTIFF image formats. It can also scale images, extract part of an image, and a few other things...
Go to the downloads area at the LizardTech site and look for "MrSID Decode"
