Abstract:
27 TerraSAR-X (TS-X) time series images with 11-day interval over the west suburb of Tianjin, China were processed using the Stanford Method for PS (STMPS). Deformation over 681,364 PS pixels was retrieved. The accuracy of TS-X derived subsidence is around 1.5 millimeters in comparison with leveling measurements. PS pixels associated with 9 transport lines were extracted. Subsidence along these transport infrastructures was presented by the dense PS pixels. This research demonstrates the potential of high resolution time series TS-X images in deformation monitoring for large linear infrastructures.
