| Abstract: | Based on Gauss projection theory,this paperdiscusses the question choosing a system of coor-dinates of engineering control networks,and gives a method of choosing a system of coordinates of GPS engineering control networks,thus ensures that engineering control networks are built in high precision.At the same time this paper discusses the survey precision of a short distance GPS altitude,and draws some beneficial conclusions. |
| Keywords: | GPS engineering control networks a system of coordinates length distorting |
