Taking the Shandong area as the study area, we use the SBAS-InSAR to process 647 views Sentinel-1A data in Shandong area between 2018.7 and 2020.4 and, according to the deformation amount and trend, reveal the hidden geological disaster points and extract the surface deformation field. In this paper, the areas with obvious ground deformation in Feicheng were selected. We combined with the field survey results, finally verified the combination of high-resolution imagery and DEM has a certain effect in the interpretation of geological disaster points.
