The imaging and topographical information in this processed view come from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter.
NASA explains the image:
The image was produced by first creating a 3-D computer model (a digital terrain map) of the area based on stereo information from two HiRISE observations, and then draping an image over the land-shape model. The vertical dimension is exaggerated by a factor of 1.5 compared to horizontal dimensions. The draped image is a red waveband (monochrome) product from HiRISE observation PSP_005787_1475, taken on Oct. 21, 2007, at 32 degrees south latitude, 141 degrees east longitude. Other image products from this observation are at http://www.uahirise.org/PSP_005787_1475.
