| 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 Québec 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). |
