This is an ortho-image of Nepenthes Mensae. The image is overlaid with elevation data from an HRSC-derived high-resolution digital terrain model (DTM).
In an ortho-image, the projecting rays are perpendicular to the plane of projection. This corrects any deformations introduced by an imaging camera. Such an image can be fitted directly on to a map.
The High-Resolution Stereo Camera (HRSC), the ESA spacecraft Mars Express obtained images focusing on a depression that displays a crater at the end of the long, winding valley, Mamers Valles.
The data was obtained on 5 August 2006 with a ground resolution of approximately 14 m/per pixel. The image is centred at approximately 39° north and 17° east on the planet.
The scale is in metres.
