【Abstract】 Taking the construction of an intercity rail transit line in Pearl River Delta as an example,this paper introduces the operation process of UAV surveying and mapping,and analyzes the application of UAV surveying and mapping results in terms of route selection,construction plan formulation,land acquisition and demolition,and large-scale topographic maping,etc.Practice has proved that the UAV mapping and surveying technology can break through the limitations of traditional mapping technology and provide the important basic data and technical support for rail transit construction.更多还原
