| 摘 要： | 随着经济的发展,城市扩建便成为必然的趋势,为解决原有坐标系存在的不足,如何选择城市坐标系便成了新的问题。在详细分析边长的高程归化以及边长的高斯投影改化的基础上,从变更中央子午线和投影面入手,提出了三种建立城市坐标系的技术方案,对测量工作者有一定的参考价值。

| Abstract: | Accompanying with the economic growth,the expanding of cities is becoming an inevitable trend.In order to solve the problems of the old coordinate system,how to establish the coordinate system of cities is the new assignment.On the basis of analyzing the projecting length deformation and Gauss projection deformation,started with changing the central meridian line and the projective plane,three different methods of establishing coordinate system in cities are put forward in this paper,which are valuable for surveyors. |

| Keywords: | projecting length deformation Gauss projection deformation compensating level surface middle meridian line |
