Radargrammetry is the science of DEM production and mapping, using defined geometry of stereo SAR sensors and GPS/GCP. Radargrammetry has been widely used to generate Digital Elevation Models (DEMs) especially for inaccessible areas. In this paper we evaluate DEMs created from stereo Radargrammetry of TerraSAR-X, in fine spotlight mode. DEM validations and statistical analysis are performed using STAR3i airborne interferometric SAR DEM and SRTM DEMs.
