Possibilities and methods of differential SAR interferometry (DINSAR) for mapping the motion of alpine ice and rock glaciers of small spatial extent were investigated. Test sites for these studies were the glacier Hintereisferner (covering 8 km2 in area) and several of its small side glaciers, and the rock glaciers Inner and Outer Hochebenkar, located in the Ötztaler mountains, Austria. For mapping the motion of the ice glaciers only one-day repeat pass SAR images from the ERS Tandem Mission, acquired during winter, were useful. 35-day repeat pass interferometric images did not show sufficient coherence. On the rock glaciers the coherence is preserved over longer periods. 35-day ERS SAR repeat pass interferograms from summer were used for motion analysis. The topographic phase was derived by differential methods using several one-day tandem pairs and applying the multi-baseline technique. The surface-parallel flow assumption was used for estimating the velocity vectors. The accuracy of the interferometric motion is assessed by comparison with field measurements and aerial photogrammetric analysis. The detail of the interferometric maps, but spaceborne DINSAR is a very cost-effective tool for comprehensive regional surveys and monitoring of ice and rock glaciers with good accuracy.
