AbstractMapping rock units and associated geological structures can be difficult to elucidate from single SAR images. Through stereoscopic examination of suitable SAR stereopairs, however, it is often concluded that recognition and interpretation geological features is greatly improved. To provide guidelines for selecting appropriate image pairs, several RADARSAT-1 images from tropical and arctic environments covering a wide range of incidence angles were examined. Best results for geological interpretation were obtained from same-side stereopairs. Where terrain relief is high, sufficient vertical exaggeration is attained with relatively small intersection angles (5-10°), whereas low relief environments require larger angles of stereo intersection (>15°). The proportion of overlap between specific beam modes is latitude dependent, thus a judicious selection of image pairs is required based on both terrain characteristics and specifications of RADARSAT-1 orbital tracks and imaging modes.
