Photogrammetrists use stereo pairs of aerial and satellite imagery to create 3D digital elevation models. Using software tools with complex algorithms, geospatial analysts can measure x, y, and z coordinates of land, buildings and various natural or man-made objects. Agencies such as NOAA (National Oceanic & Atmospheric Administration) use Planar’s StereoMirror technology for gathering information such as changes in river levels, coastal erosion or tsunami predictions. Other government agencies use stereo monitors for gathering intelligence related to defense, homeland security and disaster relief support.

One of the earliest uses of stereo photography was in the assessment of geospatial information. The International Society of Photogrammetry and Remote Sensing was established in 1910 and the American Society of Photogrammetry and Remote Sensing was established in 1934. Members of these organizations used stereo photographs to measure and analyze land terrain. Armaments secretly deployed by the Russians in the early 1960’s were identified using stereo photography during the Cuban missile crisis.
