Abstract

Abstract

By processing airborne LiDAR flight data of Jinsha River and Xiaojiang, we obtained high precision Digital Elevation Model (DEM) and Digital Surface Model (DSM). Using the digital terrain in geological structure interpretation, we may determine the distribution of active faults and the characteristics of tectonic geomorphology, delineating the range of the landslide and debris flow in Jinsha River and Xiaojiang, also estimating the area and volume of the landslide and debris flow. High precision airborne LiDAR data provides reliable information for such geological disaster warning.
