Paper Abstract

A quality assessment of InSAR topographic mapping was carried out addressing the issues of feasibility and quality in the particular case of Belgium. We first present a pre-study consisting in the selection of the most appropriate image pairs as well as an assessment of the expected DTM quality, based on interferometric baseline values and ancillary data like cloud cover, humidity, vegetation cover, relief, etc., that influence the coherence level. The quality of the DTM generated from the selected ERS-1/2 Tandem pairs is discussed by comparison with a reference DTM and put in relation with the coherence maps obtained simultaneously with the interferograms.
