ISPRS 2003 Topographic Mapping of Icy Satellites: New Methods and New Maps
Topographic mapping of icy satellites is a critical tool for evaluation of geologic problems ranging from the origin of ionian mountains to the thickness of floating ice shells. With the lack of on-board altimeters, the primary tools available for areal mapping of icy satellites are stereo image mapping and shape-from-shading (photoclinometry), to produce digital elevation models (DEMs). This report is motivated by several new developments, the most important of which are significant upgrades to our stereo topographic mapping capabilities and the successful application of 2-dimensional photoclinometry techniques to these icy surfaces.
