Using the HRSC stereo camera, digital terrain models can be derived that illustrate the topography of the region using false colours. The altitude allocation can be read from a colour scale at upper right; north is to the right in the image. Gordii Dorsum is a range of hills on Mars about 500 kilometres long, lying some 1000 kilometres southwest of the giant volcano Olympus Mons.
