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 author´s 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
