| Résumé | (disponible en anglais seulement)
In the 1960's, stereoscopic methods were first applied to radar images to derive ground elevation. Unfortunately, research uncovered contradictions and a
dichotomy between error propagation theory and practical results, particularly over high relief areas. This dichotomy combined with the lack of stereo radar pairs led to the decline of radargrammetry. The launch in 1995 of Canada's first earth
observation satellite, RADARSAT with its various operating modes and specific geometric characteristics has turned the tide. We are now able to understand and resolve this dichotomy, and to define general guidelines for selecting RADARSAT stereo
pairs for DEM generation as a function of terrain relief. |
