The USGS is producing digital elevation models (DEM) and topographic maps of Mars at scales of 1:250,000 to 1:1,000,000. The initial source material will be Viking Orbiter images, with a later transition to Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) when stereo coverage from that source is available for topographic mapping. The digital terrain models and topographic maps produced by this effort will support geologic mapping and geophysical studies. The maps will be based on the horizontal and vertical control from Mars Orbiter Laser Altimeter (MOLA). Currently, the maps are based on planetographic coordinates, but eventually planetocentric coordinates will be used.
