ISIS3 files often have the extension .cub, sometimes with an associated .lbl (label) file. When a .lbl file exists it should be used as the dataset name rather than the .cub file.
In addition to support for most ISIS3 imagery configurations, this driver also reads georeferencing and coordinate system information as well as selected other header metadata.
Implementation of this driver was supported by the United States Geological Survey.
ISIS3 is part of a family of related formats including PDS and ISIS2.
