Research on the Application of DJI M300 RTK UAV in 1∶500 Topographic Map Surveying and Mapping
With the continuous progress of oblique photogrammetry technology,various types of UAVs are constantly applied to topographic mapping.Combined with a project in Guangzhou,this paper uses DJI M300 RTK UAV for data acquisition,3D modeling and 1∶500 topographic map compilation.At the same time,the field uses the total station to collect data to carry out the accuracy analysis of the results.The results show that the aerial survey modeling results using DJI M300 RTK UAV meet the mapping accuracy requirements of 1∶500 topographic map,which is feasible and provides a good solution for the current situation and rapid update of topographic map.
