摘　　要：本文以沪昆高铁浙江段前期勘测定界控制测量为例,阐述坐标系统选择的过程,通过对投影变形值的分析,选择适宜的坐标系统,并建立了该线路的GPS平面控制网,满足勘测定界测量工作的要求。Take the boundary determination measurement of Zhejiang high-speed railway section of Shanghai-Kunming line as an example,this paper states the process on how to choose the coordinate system.Through the analysis on the values of projective deformation,an appropriate coordinate system is selected and a GPS plane control net is then established.The results show that the accuracy of this coordinate system could satisfy the survey requirement.

关 键 词：GPS控制网 沪昆高铁 独立坐标系 投影变形分析
