Abstract:

Radargrammetry is a well-established technique for deriving digital surface models (DSMs) from synthetic aperture radar images. This work focuses on the novel Staring Spotlight mode of the TerraSAR-X satellite which delivers images with a GSD down to 16 cm. Employing such images, the 2D and 3D geo-location accuracy of the physical sensor models integrated into SAR range/Doppler equations is assessed and an automated workflow for DSM extraction is presented. An analysis of the mapping potential completes this study by evaluating the DSM accuracies w.r.t. reference LiDAR data.
