In view of the shortcomings of traditional large-scale topographic map measurement methods, such as low precision, low ef-ficiency and inability to measure all-weather, in order to carry out large-scale topographic map measurement in the project, UAV air-borne LiDAR measurement system is used to quickly scan the survey area, process the data in the office, and finally compare and ana-lyze the existing topographic maps in the survey area. The experimental results show that the UAV airborne LiDAR measurement sys-tem has the advantage of fast topographic survey in mountainous areas with dense vegetation coverage, and the measurement data meet the accuracy requirements of large-scale topographic map. At the same time, it also provides reference for the idea of rapid measure-ment of large-scale topographic map in the future.
