Abstract :
The new high-resolution and full polarimetric modes of RADARSAT-2 are evaluated for digital elevation model (DEM) generation using stereo-radargrammetry with Toutin´s 3D physical model. The stereo-radargrammetric DEMs were evaluated with accurate Lidar data. Results on a test site north of Que¿bec City, Canada showed good accuracy: (2 m 1¿ horizontal and vertical) for Ultra-Fine mode (better than the resolution), and 5 m and 11 m (1¿ horizontal and vertical, respectively) for the Fine-Quad polarimetric mode (about the resolution).
