Magellan Stereo Revisted

Venus topography knowledge comes primarily from either Magellan radar altimetry with a spatial resolution of 15-20 km and a elevation accuracy of no better than 100 m or derived from radar stereo data collected by Magellan during Cycles I and III with spatial resolution on the order of half a kilometer and elevation accuracy of 20-50 m that only covered roughly 17% of the surface. We describe a previously unexploited source of Venus topography with intermediate spatial resolution and elevation accuracy to the aforementioned sources thereby extending the available Venus topographic data that uses intra-Cycle stereo observation between adjacent orbit pairs as a source of topographic data. We show that the spatial resolution and elevation accuracy are suitable for use in scientific investigations.
