Topographic image map of a part of the Utopia Planitia region
Digital terrain models of the Martian surface can be derived from data acquired by the nadir channel, which is directed vertically onto the Martian surface, and the stereo channels of the High Resolution Stereo Camera (HRSC) on Mars Express. In this colour-coded image, the absolute elevations above a reference level, the aeroid (derived from Ares, the Greek name for Mars), are depicted. These elevation values can be read based on the colour key at the top right of the image.
