Abstract :
Radargrammetry of opposite-side stereo SAR is demonstrated using Magellan SAR images of Venus. Large areas of gentle slope can be successfully matched to generate DEM using conventional stereo-match algorithm while high to moderate relief regions need further treatment using shape-from-shading. The initial stereo-match points are classified into three categories; GOOD, BAD, and TOPO, and different methods are applied to different regions to iteratively improve DEM.
