Colour-coded topographical image map of the Korolev Crater
Colour-coded topographical image map of the Korolev Crater: The image strips acquired from different angles by the HRSC camera system on board Mars Express are used to generate digital terrain models of the Martian surface, containing height information for each recorded pixel. The reference level for the altitude information is Mars. The colour coding of the digital terrain model (top right) indicates the elevation differences effectively: the topographical profile of the region covers approximately 3500 metres of elevation. The rim of the 82-kilometre-wide Korolev Crater towers around 2000 metres above the surroundings. The top of the glacier inside the crater lies a few hundred metres below the crater rim. Due to sublimation, the 1800 metre-thick domed deposit lies in a ring-shaped crater that is slightly more than two kilometres deep.
