基于机载LiDAR数据的DEM构建研究

Research on DEM construction based on Airborne LiDAR data

基于机载LiDAR(Light Detection And Ranging)数据的DEM快速构建是当前研究的热点内容之一。论文根据机载LiDAR数据的特点,基于最新开发的ENVI软件LiDAR模型,进行了DEM数据的快速构造研究。最后,根据榆树地区的LiDAR数据,通过解算等过程得到了当地的DEM数据。

It is one of the current research hotspots to quickly construct DEM with the airborne Light Detection And Ranging （LiDAR） data. In this paper, the DEM is quickly constructed with LiDAR modular of ENVI software according to the characteristics of the airborne LiDAR data. Finally, the DEM data is obtained quickly with the method for Yushu area of Jilin province with the airborne LiDAR data.
