五家渠城市平面坐标系统的建立

Establishment of Urban Coordinate System in Plane of Wujiaqu

根据大地测量学的原理,简要叙述了建立城市坐标系三种方法的理论依据、计算公式及各自的缺点,在此基础上提出以任意带坐标系的方式建立五家渠城市坐标系,并计算出城市坐标系的中央子午线经度、抵偿范围和城市坐标系与国家统一3°带坐标系间相互转换的方法。

In this paper,the theoretic foundation ,calculate formula and respective defect of three methods for establishing urban coordinate system is been discussed according to the theory of geodesy, And then the longitude of central meridian and width of compensation effect of urban coordinate system is been calculated. At last,the methods of transform each other between urban coordinate system and universal nation three-degree zone coordinate system is been raised.
