摘要
本文在边长的高程归化以及边长的高斯投影改化详细分析的基础上,从变更中央子午线和投影面入手,对城市坐标系建立的方法进行了对比分析。
On the base of analysis of deformation of length projection and deformation of Gauss projection,the methods of establishing the plane coordinate system in cities are analyzed in this paper by changing the central meridian line and the projective plan.
