Many Dutch polders are subject to subsidence due to groundwater lowering. Rijkswaterstaat studies the potential of using Synthetic Aperture Radar (Repeat Track Interferometric techniques) for subsidence monitoring. In this project DCRS has processed three data sets from Foulum, Jutland. Single look complex data and various interferometric products have been delivered to Rijkswaterstaat.
