In order to effectively carry out land subsidence evaluation,this paper takes the radar remote sensing satellite data as the basis,and through the reasonable application of Interferometric Synthetic Aperture Radar(InSAR)technology,extracts the surface deformation information from January 2017 to May 2022 in the survey area of Xuwen County,interprets the land subsidence information and dangerous slopes in Xuwen County,and combines the InSAR surface deformation monitoring results to further determine the characteristics and threat range of disaster activities,achieving early identification of slope geological disasters.
