Evaluation of ESA's Extended Timing Annotation Dataset (ETAD) for Sentinel-1 - First Results for Ice Velocity Monitoring and InSAR Applications in Greenland, Iceland and Norway
SAR images benefit from excellent geometric accuracy due to accurate time measurements in range and precise orbit determination in azimuth. Moreover, the interferometric phase of each single pixel can be exploited to achieve differential range measurements for the reconstruction of topography and th...
