The Integrated System for Imagers and Spectrometers (ISIS) is a free, specialized, digital image processing software package developed by the USGS for NASA. ISIS's key feature is the ability to place many types of data in the correct cartographic location, enabling disparate data to be co-analyzed. ISIS also includes standard image processing applications such as contrast, stretch, image algebra, filters, and statistical analysis. ISIS can process two-dimensional images as well as three-dimensional cubes derived from imaging spectrometers. The production of USGS topographic maps of extraterrestrial landing sites relies on ISIS software. ISIS is able to process data from both 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.
