Tharsis Tholus in perspective

November 18, 2011
Tharsis Tholis towers 8 km above the surrounding terrain with a base that stretches 155 x 125 km and a central caldera measuring 32 x 34 km. The image was created using a Digital Terrain Model (DTM) obtained from the High Resolution Stereo Camera on ESA’s Mars Express spacecraft. Elevation data from the DTM is colour coded: purple indicates the lowest lying regions and beige the highest. The scale is in metres. In these images, the relief has been exaggerated by a factor of three.
