ISIS Documentation

Integrated Software for
Imagers and Spectrometers

Some ISIS Docs have Moved

ISIS documentation, including ISIS tutorials, guides, and concepts, has been moved to USGS Astrogeology Software Docs. Manuals for each ISIS Application remain here, as do docs for previous ISIS versions, accessible via the left panel.

What is ISIS?

Integrated Software for Imagers and Spectrometers (ISIS) is free and open-source software (FOSS) developed by the USGS Astrogeology Science Center for NASA and the planetary community. ISIS is a fundamental tool for processing raw archival data into analysis ready products and includes standard image processing tools such as contrast, stretch, image algebra, filters, and statistical analysis. However, ISIS's key feature is the ability to place different types of data in the correct cartographic locations on extraterrestrial bodies. The cartographically located data can then be used to create archives, topographic or cartographic maps, digital elevation models, and other scientific products.

Supporting Planetary Space Missions

ISIS is a valuable resource for planetary missions that require systematic data processing, products for planning, and research and analysis of derived data products. Support for a mission is added to ISIS by creating sensor models, tools for ingesting mission-specific ancillary data, and optional tools for calibrating mission data. Once a mission is supported, data from that mission can be used with the full suite of processing and analysis tools in ISIS. ISIS supports data from NASA and International spacecraft missions including Lunar Orbiter, Apollo, Voyager, Mariner 10, Viking, Galileo, Magellan, Clementine, Mars Global Surveyor, Cassini, Mars Odyssey, Mars Reconnaissance Orbiter, MESSENGER, Lunar Reconnaissance Orbiter, Chandrayaan, Dawn, Kaguya, and New Horizons.
