摘要:
通过机载LiDAR飞行数据处理，获得飞行区内高精度的数字高程模型（DEM）和数字地表模型（DSM）等数字地形成果，应用数字地形进行地质构造解译，确定小江活动断裂展布及构造地貌特征，圈定飞行区内金沙江、小江的滑坡及泥石流的分布范围，估算其面积及体积，为此类地质灾害的预警提供可靠信息。
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.
