MrSID (pronounced Mister Sid) is an acronym that stands for multiresolution seamless image database. It is a file format (filename extension .sid) developed and patented by LizardTech (in October 2018 absorbed into Extensis) for encoding of georeferenced raster graphics, such as orthophotos.
MrSID originated as the result of research efforts at Los Alamos National Laboratory (LANL).
