Anaglyph images can be generated from data acquired by the nadir channel of the DLR-operated HRSC camera system on ESA's Mars Express spacecraft, which is directed perpendicularly to the surface of Mars, and one of the four oblique stereo channels. When used with red-blue or red-green glasses, they allow a three-dimensional view of the landscape and give the viewer a spatial idea of the differences in altitude. In this way, many of the geological structures described can be better understood than in the vertical plan view.
