坐标换算程序设计及实现

摘要

Our common coordinate systems are as follows—Beijing Geodetic Coordinate System 1954,National Geodetic Coordinate System 1980,World Geodetic System — 1984 Coordinate System,and China Geodetic Coordinate System 2000.In this paper,we deeply research the above-mentioned four kinds of coordinate systems,and the focus of research is in the same basis of reference,including a space rectangular coordinates,geodetic coordinate conversion,Gauss coordinates conversion and Neighbor with conversion.Based on Visual Basic 6.0 programming language,this paper develops the corresponding coordinates conversion software,and the existing data processing results show that the design is reasonable and the software' s feasibility is better.%我国常用的坐标系有如下几种:1954年北京坐标系、1980年国家大地坐标系、WGS-84世界大地坐标系、2000国家大地坐标系.本文对上述四种坐标系进行了深入研究,重点研究在同一参考基准下的坐标换算,涉及的内容有空间直角坐标同大地坐标相互换算、高斯坐标正反算以及邻带换算.本文以Visual Basic 6.0为编程语言,研制了相应的坐标换算软件,现有的资料处理结果表明程序设计是合理的,软件可行性较好.
