A new photoclinometric technique for extraction of topographic data from single planetary images is presented that overcomes many previous limitations. The procedure fully compensates for oblique viewing geometry prevalent in spacecraft images. Albedo variations have been overcome in the topographic solution by simultaneously utilizing brightness data from a pair of profiles. Test results indicate an accuracy and precision of approximately 2o for slopes of typical bowl-shaped craters, which translates to approximately 5% for depths.-from Authors
