摘要
基于大地坐标全微分公式探讨了北京1954坐标系和西安1980坐标系之间的相互转换问题,对常用的3参数法和7参数法做了一些改进,并基于湖北省内的控制成果做了大量的实验分析,进而总结了获得参数法最佳转换结果的一些条件。
The paper discusses transform between Bejing54 and Xi＇an80 coordinates system based on the whole differential equation of geodesic. And some improvement has been made in the 3 parameter method and 7 parameter methods. And some requirements to gain the best transforming precision have been gained through the experimentation based on the control survey production in Hubei province.
