| Summary: | INTRODUCTION Polar regions play an important role in the global environment. The potentiality of SAR interferometry for the monitoring of high latitude areas is today a well understood geophysical tool and represents a flexible and powerful method to study large polar sectors at low specific cost. We have used pairs of tandem images of satellites ERS-1 and ERS-2 synthetic aperture radar (SAR) of the David glacier (DG), East Antarctica, for the purpose to outline the grounding line. Synthetic aperture radar data have been provided under the VECTRA project cover (European Space Agency Announcement Opportunity 3.108) in raw format. The raw data have been focalised with phase preserving algorithms to obtain single look complex (SLC) images, coherence maps and interferograms. The procedure adopted for ice velocity computationis based on differential interferometry of the monodimensional ice velocity field of the DG, the largest outlet glacier of Victoria Land. An interpretation of the g |
