MG2 and MG3 are MrSID format files and they both have the file extension of “.sid.” MG2 stands for MrSID Generation Two and MG3 stands for MrSID Generation Three. GeoExpress can create MG2 and MG3 files, with MG3 supporting the latest cutting-edge technology from LizardTech, such as lossless and improved lossy encoding, updating MrSID mosaics and mosaicking existing MrSID tiles.
