The complex caldera of Olympus Mons on Mars

This perspective view shows the complex caldera (volcanic crater) of the Olympus Mons volcano on Mars. The image has been calculated from the digital elevation model derived from the stereo channels and combined with the nadir- and colour- channels of the High Resolution Stereo Camera (HRSC) on ESA’s Mars Express.

The data has been retrieved from a height of 273 km in orbit 37 on 21 January 2004.
The view is centred at 18.3°N and 227°E. The image is 102 km across and has a
resolution of 12 m per pixel. The vertical exaggeration is 1.8. South is up.
