Research on the application of ArcGIS in urban digital mapping
At present,most of the surveying and mapping structures of urban digital maps are set as targets,and the scope of surveying and mapping is limited,resulting in increased relative surveying and mapping errors.Therefore,this paper proposes the application analysis and practical research of ArcGIS in urban digital map surveying and mapping.The test results show that compared with the iteration of traditional GCV,Tikhonov regularization city digital map mapping group and traditional knapsack 3D laser scanning city digital map mapping group,with the assistance of ArcGIS architecture,the current design of the digital map mapping effect is better,more targeted,and has practical application value.
