Abstract :
ERS tandem mode differential synthetic aperture radar (SAR) interferometry (InSAR) is used to measure the surface flow field of a mid-latitude alpine glacier. The interferometric imaging geometry was reconstructed using accurate orbit data and a digital elevation model (DEM) derived from the CCRS CV-580 cross-track InSAR. The flow field is favorably validated against historical and nearly coincident displacement measurements made using surveying techniques
