What is drone mapping
UAV surveying and mapping refers to the process of using UAVs (Unmanned Aerial Vehicles, UAVs) equipped with high-precision sensors to collect and process data on the surface through aerial photography, lidar and other technical means to generate high-precision maps, three-dimensional models or other geographical information data. In recent years, with the rapid development of drone technology, drone surveying and mapping have been widely used in land survey, urban planning, disaster monitoring and other fields.
