Abstract:Three InSAR products and DEM data are involved in detecting potential landslides over Wudongde Hydropower station section, Jinshajiang. Several known and unknown landslides are successfully detected, and their spatial patterns and stabilities are detected, showing that this procedure is an efficient means to detect active landslides in a large area. Meanwhile, small baseline subsets InSAR technique is applied to monitor the Jinpingzi landslide. Both spatial zonation features and time-series deformation results in key landslide zone are achieved. The InSAR precision in slide direction is 1.8 cm by comparing with in-situ total station measurements. Different InSAR techniques are illustrated in this paper for different scale landslide applications.
