Three Gorges Project (TGP), the largest hydroelectric project in the world, is one of the most significant constructions in China. Since the TGP greatly changed the natural terrain of the upriver gorges, the regular surveys over this region with the earth observation images are highly needed. The multi-image InSAR analysis has proven to be a very capable and effective technique for obtaining precise elevation and displacement measures of the detected targets. In this work, more than one hundred InSAR images have been processed to measure and analyse the topography and deformation...
