Interferograms were generated from 10 TerraSAR-X image pairs, with the objective of obtaining estimates of winter surface motion for a slow-moving polythermal arctic glacier. Flow directions were computed using both ascending and descending-pass interferograms for each period, with the median value being adopted as the final direction. The weighted average(More)
Measurements of surface displacement made using GPS, SAR interferometry, and ground-based photogrammetry were compared for a number of targets located close to the terminus of a polythermal arctic glacier. The results showed that average measurements for the winter period made using GPS and SAR interferometry agreed well at most locations. Horizontal and(More)
