Abstract

The stereo processing of Magellan SAR imagery into digital elevation maps is presented. The algorithms used and their implementation on a parallel transputer architecture is explained. Results are given along with the effects of using mosaicked imagery and of errors in the spacecraft ephemeris. Ways of improving the knowledge of the spacecraft ephemeris are described
