Abstract: In recent years,with the accelerating process of urbanization construction,the difficulty of urban basic management also increases.As an important measure in the process of urban informatization development,digital city management project plays a significant role in improving the level of urban management.Vehicle-borne LiDAR measurement technology is relatively mature in China,and it can improve the capabilities of city component data acquisition.This paper studied the application of vehicle-borne LiDAR in urban component acquisition.By comparing with the traditional CORS measurement data,the technical process and the accuracy of point cloud data were analyzed in detail,which provided a new method for the acquisition of urban components in digital urban management.

Key words: digital city management, CORS, vehicle-borne LiDAR, accuracy analysis
