Geographic information mapping method based on unmanned aerial vehicle remote sensing technology
This paper proposes a geographic information mapping method based on unmanned aerial vehicle(UAV)remote sensing technology,using the example of the geographic information mapping task in Qixingguan District,Guizhou Province,China.By analyzing the terrain conditions in Qixingguan District,a UAV remote sensing technology mapping process was designed.Based on the actual topographic fluctuations in the survey area,appropriate aerial photography equipment was selected,and the UAV's flight altitude was calculated,and flight paths were designed to complete aerial surveys of terrains with varying degrees of undulation.Remote sensing images were processed using an image enhancement method based on local variance equalization,and then mosaicked and clipped to produce orthophotos of the region.Through analysis of the mapping results,it was demonstrated that this method can effectively complete geographic information mapping in the study area,providing a reliable basis for natural resource management.
