Abstract :
This paper briefly describes how multi-incidence RADARSAT SAR images can facilitate geological interpretation. The authors´ research has shown the importance of selecting the most appropriate SAR viewing geometry for geological and geomorphological mapping. This selection is based on local topography and terrain conditions. For instance, in high relief areas, incidence angles varying from 40 to 59 degrees are suitable for structural and geomorphic mapping. Incidence angles, varying from 20 to 35 degrees are suitable for the moderate relief of shield terrains. A wide range of incidence angles, varying from 25 to 45 degrees, are suitable for the flat sedimentary terrains. In situations where the topography is quite variable within a single scene, stereo viewing can facilitate geological interpretation
