Recent Advances and Prospects in Extraterrestrial Planets Mapping

The topographic mapping of extraterrestrial planets provide basic geospatial data for engineering missions and various planetary scientific research, which can be used to select landing sites, plan path of rovers and conduct planetary geological and geomorphological analysis. We summarize the representative topographic mapping techniques and products in the exploration missions of moon, Mars and asteroids. This paper focuses on the research status of the techniques of generating digital orthophoto map and digital elevation model using mapping camera and LiDAR. We also give some suggestions on standard setting, data sharing, key technical bottlenecks and data processing technology system of extraterrestrial planets mapping.
