Colour-coded topographic map showing the northeast of Noctis Labyrinthus
Digital terrain models of the Martian surface can be construed with a resolution of down to 10 metres per pixel with data acquired by the nadir channel, which is directed vertically onto the Martian surface and the oblique views obtained by the stereo channels of the High Resolution Stereo Camera (HRSC) on board Mars Express. In this colour-coded image, the absolute elevations above a reference level, the aeroid (derived from Ares, the Greek word for Mars), are well depicted. Using the colour scale in the upper right of the image, the enormous differences in elevation – up to 6000 metres – between the blue valley floors and the pink and brown elevated plateaus of the mesas are apparent.
