Description :
The results presented show how glacier velocities can be measured and calculated from Earth Resources Satellite (ERS) tandem interferometric synthetic aperture radar (InSAR) data by the use of geographical information system (GIS) and non-interferometric software. A semi-automatic algorithm is applied to a data set covering glaciers from the arctic archipelago Svalbard. Estimated DinSAR velocities are decomposed into the glacier surface flow direction using a digital elevation model (DEM). Velocity fields for the glaciers Isachsenfonna, Akademikerbreen and Nordbreen on Svalbard are presented.
