Description: PIA02031: Maps of Mars Global Topography - Maps of Mars' global topography. The projections are Mercator to 70° latitude and stereographic at the poles with the south pole at left and north pole at right. Note the elevation difference between the northern and southern hemispheres. The Tharsis volcano-tectonic province is centered near the equator in the longitude range 220° E to 300° E and contains the vast east-west trending Valles Marineris canyon system and several major volcanic shields including Olympus Mons (18° N, 225° E), Alba Patera (42° N, 252° E), Ascraeus Mons (12° N, 248° E), Pavonis Mons (0°, 247° E), and Arsia Mons (9° S, 239° E). Regions and structures discussed in the text include Solis Planum (25° S, 270° E), Lunae Planum (10° N, 290° E), and Claritas Fossae (30° S, 255° E). Major impact basins include Hellas (45° S, 70° E), Argyre (50° S, 320° E), Isidis (12° N, 88° E), and Utopia (45° N, 110° E). This analysis uses an areocentric coordinate convention with east longitude positive. Color coding on this map of the planet Mars indicates relative elevations based on data from the Mars Orbiter Laser Altimeter on NASA's Mars Global Surveyor. Red is higher elevation (up to +8 km and higher); yellow is 0 km; blue is lower elevation (down to -8 km). In longitude, the map extends from 70 degrees (north) to minus 70 degrees (south). The east-west axis is labeled at the bottom in degrees of east longitude, with the zero meridian at the center. Data was produced by the Mars Global Surveyor's MOLA instrument Producer ID: P50409 MRPS95009
