This image, taken by the Mars Express High Resolution Stereo Camera, shows the region of Ariadnes Colles on the Red Planet.
The data was acquired on 16 April 2007 in the region of Ariadnes Colles that lies at about 34° south and 172° east. The ground resolution is about 13 m/pixel.
This ortho-image was rectified using elevation data derived from a high-resolution Digital Terrain Model, or DTM (obtained from HRSC data), such that distortions introduced during imaging are corrected. Such an image can be used to derive maps. Elevation data from the DTM has been colour-coded and overlain on the ortho-image so that elevation data and the image itself are displayed in a single scene.
The scale is in metres.
