Topographic mapping of the Mars MC quadrangles using HRSC data

Abstract

Since 2010 new HRSC multi-orbit data products have been generated, which have been developed into a global mapping program organized into MC-30 half-tiles, since 2014 [4,5]. Based on continuous coverage of an area, regional DTMs and orthomosaics can be produced by combining image data from multiple orbits using specifically adapted techniques for block-adjustment, DTM interpolation and image equalization [6]. The resulting DTMs and color orthomosaics are the baseline for a controlled topographic map series of Mars at a scale of 1:700,000. The extents of the regional products follow the MC-30 (Mars Chart) global mapping scheme of Greeley and Batson (Fig. 2) [7], which subdivides Mars into 30 quadrangles. All maps are available for the public at the HRSC team website (http://hrscteam.dlr.de/HMC30/index.html).
