False colour topography of the Kasei Valles mouth region
Digital terrain models of the Martian surface can be created with an accuracy of up to 10 metres per pixel from the nadir channel, directed vertically onto the Martian surface, and the stereo channels of the HRSC camera. In this colour-coded image, the absolute elevations above a reference level, the areoid (derived from Ares, the Greek word for Mars), are shown. These elevation values can be read based on the colour scale at the top right of the image. The maximum difference in elevation values amounts to over 2000 metres.
The elevation differences illustrated in colour clearly show the residual ejecta blanket of Worcester Crater in the left half of the image. North is to the right in the image.
