Demonstration And application of New "three check" system Based on Comprehensive Remote Sensing Recognition of Geological Hazards—Taking the "red layer" area of Yuanma Basin of Hunan Province as an example

The applicability of the new“Three check” system for geological hazards is verified in the“Red bed area” of Yuanma basin by using multi-source remote sensing data and technical means such as INSAR, LiDAR and optical images. This paper explores the establishment of a technical method system for identifying geological hazards in mountainous and hilly areas of South China based on integrated remote sensing, which provides basic data and technical support for accurate identification and control of geological hazards.
