Abstract :
The results presented show how glacier velocities can be measured and calculated from ERS tandem INSAR data. A semi-automatic algorithm using existing and new implemented moduls in the GIS package Arc/INFO has been developed for the calculation of glacier velocity. The velocities are decomposed into the flow direction of the glacier using an external DEM. Velocity fields for the glaciers Isachsenfonna, Akademikerbreen and Nordbreen at Spitsbergen have been calculated
