Paper Abstract

NASA's project to map planet Venus in the Magellan mission has become a great success, resulting in an unprecedented set of radar images covering the entire planet, much of it with more than one image. While not part of the nominal mission plan and original NASA program, this data set has been demonstrated to support the extraction of detailed topographic data with accuracies in the range of perhaps +/- 200 m. We discuss in this paper the techniques which were used so far to obtain such data, and we support the proposal to use the Magellan image data set to develop a topographic elevation model of all areas covered by multiple images. This will not only result in topographic data, but also in a set of co-registered and ortho-rectified images which can be the basis of a unique and modern image data base and information system about the planet for use by future generations of planetary scientists.
