The Viking Orbiter and Viking Lander spacecraft have thus far returned several thousand images of Mars from orbit and from the surface. The Orbiter spacecraft are equipped with vidicon systems and the Lander spacecraft utilize facsimile cameras with photosensitive diode arrays. JPL's Image Processing Laboratory processed both Orbiter and Lander imagery in support of mission operations and science analysis. Digital processing included enhancement, geometric projection for a variety of applications, and mosaicking. The Orbiter cameras obtained stereo views of portions of the Martian surface by viewing the same portion of the surface at different viewing angles as the spacecraft passed overhead. Orbiter stereo imagery was processed to produce elevation maps of large portions of the surface. Each Lander spacecraft had two cameras positioned approximately one meter apart that provided stereo coverage of a portion of the field of view around each Lander spacecraft. Lander stereo imagery was processed to produce elevation profiles and isoelevation contours of the surface surrounding each Lander.
