| Abstract | RADARSAT has 35 different beam and incidence angle positions with spatial resolution varying from 10-100 m. In order to maximize its use for geological and geomorphological mapping, it is necessary to
evaluate the various beam modes and report on their suitability. The study areas were selected to represent different terrain types and surfaces in Canada. The terrain types represent low, moderate and high relief. These surfaces are typical of
rugged, forested, mountainous terrains; glaciated, forested Precambrian shield terrains; and partly vegetated, flat to rolling prairie landscapes. Our results have shown that selected RADARSAT viewing geometry is significant for the delineation
of geological structures, lithological units, landforms and terrain types. In mountainous terrains, incidence angles varying from 40-59 degrees, are suitable for structural and geomorphic mapping. Small incidence angles, varying from 20-31 degrees,
are suitable for the Precambrian shield terrains. A wide range of incidence angles, varying from 25 to 45 degrees, is suitable for the flat and rolling prairies. |
