Photogrammetric analysis of Clementine multi-look angle images obtained near Mare Orientale

A local control point network and a DTM (Digital Terrain Model) are derived from Clementine UVVIS multi-look angle images that were obtained on April 30, 1994, covering a small region of the Lunar Orientale Basin (19.5 degrees S to 15 degrees S adn 84.5 degrees W to 86.0 degrees W). The nominal camera pointing and spacecraft trajectory data were photogrammetrically adjusted, a procedure which was found to improve estimates of the coordinates of 41 control points significantly to an internally consistent accuracy of 30 m in the horizontal and 50 m in the height direction. The terrain model correlates well with features identified in the image data, two craters, volcanic constructs, and the dark lava-filled Lacus Veris, located in a topographic depression. The terrain model indicates a steep 2000 m drop in elevation within a range of only 6-8 km towards the center of Orientale. Further studies of the lunar topography in this particular region using Clementine stereo data seem well warranted and feasible. Copyright (C) 1996 Elsevier Science Ltd
