AbstractThis paper considers the topographic measurement and analysis basing on multi-baseline Synthetic Aperture Radar data. In 2009, the ongoing works were focused on taking advantage of Permanent Scatterers (PS) Interferometry to estimate the terrain elevation and ground motion in not urban contexts. An adapted version of the method, namely Quasi-PS (QPS) technique, has been used in order to exploit the distributed target information. One of the analyzed datasets concerns the mountainous area around Zhangbei, Hebei Province, from which a geocoded Digital Elevation Model (DEM) has been retrieved. Regarding ground motion monitoring, our attention was focalized on two different areas. The first is a small area near the Three Gorges Dam, in which ground deformations have been identified and measured. The second area regards the west part of the municipality of Shanghai, centered on a straight railway. The subsidence in that zone has been measured and the interferometric coherence of the railway has been studied, according to the hypothesis of spatial and temporal stability of this kind of target.
