摘要
为加快建设数字化城市工作的进程,强化规划、国土等部门用地管理的工作协调及信息共享,广州市推进了广州市平面坐标与1980西安坐标系的“一图双坐标”重点工程。本文针对两种坐标系统的联测、转换参数的求取、转换程序的编制以及精度检测等关键性技术问题进行了研究和解决,并从中得出了有益的结论。
In order to speed up the construction of ＂Digital- city＂ and strengthen the management coordination as well as information sharing between Municipal Bureau of Planning and Municipal Bureau of Land Resources, the so - called ＂Twin Map Coordinate Systems＂ project was carried out in Guangzhou city using the Guangzhou Coordinate System and the Xian Coordinate System 1980. This paper studied and solved the key problems of connection survey, determination of transformation parameters, programming of transformation software and analysis of accuracy. Some useful conclusions were also drawn by the authors.
