摘要
以某面积为14 km2的丘陵地貌1∶500地形图测绘项目为例,介绍使用机载激光雷达进行外业高程点数据采集,使用专业数据处理软件进行点云数据处理,最终获得符合要求的地面点.为验证机载激光雷达测量成果精度,使用多种测量方式对成果精度进行检查.验证了机载激光雷达在1∶500地形图测量工作中应用的可行性.
Abstract
Taking the 1:500 topographic mapping project of hilly terrain based on a certain area of 14km2 as an example,this article in-troduces the use of airborne LiDAR for field elevation point data collection,and the use of professional data processing software to process point cloud data,ultimately obtaining ground points that meet the requirements. To verify the accuracy of airborne LiDAR measurement re-sults,multiple measurement methods are used to check the accuracy of the results. This paper verified the feasibility of applying airborne Li-DAR in 1:500 topographic map measurement work.
