The map shown here was created using an image mosaic made from single orbit observations of the High Resolution Stereo Camera (HRSC) on board ESA’s Mars Express mission. The color mosaic consists of two orbit strips (5252, 5270) and covers an area at about 18 degrees latitude and 77 degrees longitude north of the Martian equator. The color-coded topographic map is based on a digital terrain model (DTM) of the region, from which the topography of the landscape can be derived. The reference body for the HRSC-DTM is a Mars equipotential surface (Areoid).
HRSC is a camera experiment that was developed and is operated by the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR).The systematic processing of the camera data took place at the DLR Institute for Planetary Research in Berlin-Adlershof. The working group of Planetary Science and Remote Sensing at Freie Universität Berlin used the data to create the image products shown here.
