Abstract
DEM generated from RADARSAT images are evaluated. Results show that the only parameter that has a significant impact on the precision is the type of the relief: 20-25 m and 35-40 m with 90% of confidence for low and moderate relief respectively, whatever the stereo-pair. It also shows that the base-to-height ratio is not a good indicator for predicting the accuracy with SAR stereo-images
