SURFACE SUBSIDENCE MONITORING IN GANZHOU AREA BASED ON SBAS-INSAR

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2022
Abstract. In this paper, we first obtained the temporal-spatial changes of surface subsidence in Ganzhou area based on SBAS-InSAR technology using 24 scenes Sentine-1A images covering the Ganzhou area from 2018 to 2020. Then we studied the surface subsidence characteristics in the study area.
