As the first group of civilian interference satellites in China, LT1 satellite has provided reliable data support for normalized monitoring and identification of geological hazards through comprehensive remote sensing. In order to verify the deformation monitoring effect of LT1 satellite in the hilly and mountainous areas with dense vegetation coverage in Jiangxi province, a comprehensive remote sensing identification method combining Stacking technology and optical remote sensing interpretation has been used to identify geological hazards in Pingxiang area in Jiangxi Province. A total of 195 suspected hidden danger points have been identified, and 46 hidden danger points have been confirmed through field verification. It is indicated that LT 1 satellite data in Band Mode 2 performs well in identifying hidden dangers, such as ground subsidence, collapse and subsidence. It can identify small landslide hazards in densely vegetated areas and has good applicability for identifying medium and above landslide hazards.
