Özet
This paper addresses digital elevation mode (DEM) generation with RADARSAT synthetic aperture radar (SAR) fine mode images (F2-F4 and F1-F5) over high relief areas. Shallow look angles and small intersection angles were chosen to reduce layover and radiometric differences in the stereo images and thus increase the performances of the image matching. The radar-grammetric DEM's are thus evaluated as functions of processing methods (stereo viewing and editing) and different geometric parameters (intersection angle and derivative topographic surfaces).
