摘要
本文简述了新型城市坐标系参数反演算法及其在广州2000坐标系建立中的具体实践。通过研究坐标统一、新型城市坐标系参数反演算法、广州2000西带坐标与广州西带坐标等同使用的检核、坐标参数求取及其转换软件编制等多个方面内容,创建了广州2000坐标系,实现了城市测绘基准统一,形成了城市平面坐标系统建立新型解决方案。
This paper briefly describes the coordinate transformation parameter inversion algorithm of new urban plane coordinate system and its concrete practice in the Guangzhou 2000 coordinate system.The Guangzhou 2000 coordinate system are created by studying the coordinate unification,the parameter inversion algorithm of new city coordinate system,the equal application check of Guangzhou 2000 west belt coordinate and the Guangzhou west belt coordinates,coordinate transformation parameter calculation and relevant software compilation.It realizes the unification of urban surveying and mapping datum,and to become a new solution for urban planar coordinate system.
