Topographic image of Rabe Crater
Topographic image of Rabe Crater
Topographical terrain models can be computed using stereo image data from the HSRC camera system, which is operated by DLR. In the absence of ‘sea level’, the elevation data is referenced to an areoid – a modelled equipotential surface on which everything experiences the same gravitational attraction towards the centre of the planet. The grey and red areas are highest, the dark blue and purple coloured areas are the lowest. The data used to create this image was acquired by the High Resolution Stereo Camera (HRSC) during orbits 2441 and 12,736 of Mars Express. The image resolution is about 15 metres per pixel.
