The differential interferograms presented here were generated from RADARSAT-2 Synthetic Aperture Radar data using Differential Interferometric Synthetic Aperture Radar (DInSAR) methodology. The processing was carried out using GAMMA software (Wegmüller and Werner, 1997) and involved several steps: coregistration and resampling; interferogram calculation, including the removal of the topographic phase using the 30 m ASTER DEM; adaptive filtering (Goldstein and Werner, 1998); phase unwrapping (Costantini, 1998); and geocoding.
