Acquisition and Accuracy Check of Airborne LiDAR Point Cloud Data from Large Scale Topographic Maps
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.
