The cartographic processing of planetary image data has a long history within the Astrogeology Program. The software used in the processing has evolved numerous times since the early 1970's to keep up with the steady advances made in computing technology. In the latest version (Isis 3), applications have graphical user interfaces (GUIs) in addition to running on the command line, increasing user-friendliness while maintaining batch processing and scripting functionalities. The fully documented API (application program interface) allows developers to quickly write new applications without needing to learn GUI programming or know the mechanics of reading and writing various file formats.

The following packages are no longer supported and maintained, but are still in use. Documentation is provided below for our legacy software users.
