Application of Rotor UAV LiDAR in Marine Beach Mapping

Abstract This paper based on the Jiangsu Provincial Offshore Underwater Geographic Information Data Acquisition Pilot (North) project, uses the Dajiang M600 Pro six rotor UAV equipped with the Haida Digital Cloud ARS-200 airborne LiDAR equipment to acquire topographic data of the marine mudflats, and then Terrasolid software is used to process the data to obtain the point cloud results and DEM results of the marine mudflats, and finally, GPS-RTK is used to collect the check points of the surveyed area to check the accuracy of the results. The results show that the precision of point cloud results is better than ± 10cm, which verifies the feasibility of rotary-wing UAV LiDAR technology applied to marine beach mapping, and provides a new technical scheme for marine beach mapping.
