Abstract

Differential Interferometric Synthetic Aperture Radar (D-InSAR) is used to monitor the land subsidence of Xi'an City, China over the period of 1992-1993. Four different interferometric pairs are used to calculate land subsidence rates over the monitored area. A high resolution external DEM and precise satellite orbit data are adopted to remove the topographic effects on interferograms in the D-InSAR processing. Historical leveling measurement results are used to assess the D-InSAR results by overlaying the 2-D subsidence patterns from D-InSAR and subsidence profiles from leveling measurements.
