Abstract:

To reliably monitor the deformation of a single landslide is often a difficulty for DInSAR with mid-resolution SAR data. The high resolution SAR systems bring opportunities for the task. Among the landslides in Three Gorges area, Shuping landslide is typical and some previous works using DInSAR have been done during the last years. In this paper, 9 TerraSAR-X spotlight images are used to map the surface displacement of Shuping landslide. Conventional and coherent pixels based DInSAR are both applied. The deformation field of the landslide is mapped and 2 deformtion cones are identified. Meanwhile, this paper gives out the average deformation velocities of the coherent pixels during the period from January to March 2012. It is confirmed that DInSAR can become a valuable tool in studying and monitoring single landslides with high resolution SAR images. In the future, the DInSAR measurements along the line of sight direction should be converted to real slide direction of the landslide and analyzed joint with multi-source data.
