The colour-coded topographic view shows relative heights and depths of terrain in the Meridiani Planum region on Mars. Red and white represent the highest terrain, and blues and purples show lower terrain, such as the interiors of craters (see key).
A relatively flat and smooth region towards the centre of the image has been chosen as the landing site for the ExoMars Entry, Descent and Landing Demonstrator Module.
The image is based on a digital terrain model of the region, from which the topography of the landscape can be derived. The view comprises four images taken by the High Resolution Stereo Camera on Mars Express on taken on 23, 26 and 29 August 2005, and 1 August 2010, and covers a region 352.5°–356.5°E and 4.5°S–0.5°N.
