The colour-coded topographic view shows relative heights and depths of terrain in the Arda Valles region on Mars. Red and white represent the highest terrain, and blues and purples show lower terrain (see key).
The image is based on a digital terrain model of the region, from which the topography of the landscape can be derived. The region was imaged by the High Resolution Stereo Camera on Mars Express on 20 July 2015 during orbit 14649. The image is centred on 19°S / 327°E; the ground resolution is about 14 m per pixel.
