摘要
以江西湖南交界处某矿山测量为例,介绍机载激光雷达技术在地形复杂测区DEM生产中的应用。首先利用机载激光雷达进行数据获取,然后再对数据进行处理得到精准的点云数据并制作DEM产品,最后通过对数据进行对比分析,得出成果的定位精度能满足规范要求,且能缩短工期的结论。
In this paper,taking a mine project at the junction of Hunan and Jiangxi as an example,the application of Airborne Lidar Technology in the DEM production in a complicated topography area is introduced. First of all,Airborne Lidar is used for the data acquisition,and then the acquired data are processed to get accurate point cloud data and produce DEM products. Finally,through comparison and analysis of the results,it is concluded that the positioning accuracy of the results can meet the requirements of the specification,and shorten the duration of the project.
