| Abstract: | Length deformation is inevitable in GPS control surveying.In order to meet the need of engineering surveying,this paper introduced the program of constraining the projection deformation.At the same time based on the principle of barycentric coordinates,the paper proposed the processing methods of projection deformation between two different plant area to keep the internal precision of GPS control net. |
