摘要
在介绍似大地水准面精化技术的的基础上,论证了在上海西部郊县地区应用GPS水准法确定区域似大地水准面的可行性,并通过确定上海嘉定、青浦两区的似大地水准面证明了用GPS水准法确定的似大地水准面精度可满足地下管线测绘工作的需要。
On the basis of introducing the accuracy quasi-geodic surface technique, the possibility of surveying regional quasigeodic surface by the GPS-leveling technique in the west county of shanghai is discussed in the paper. It is proved that the precision of quasi-geodic can meet the demand of the underground pipeline-surveying project by computing the quasi-geodic in jiading and qingpu county of shanghai.
