摘要
采用Matlab软件进行坐标转换程序设计,实现了3种椭球的大地坐标与直角坐标的互换计算、高斯投影正反算、七参数解算、不同坐标系统之间的七参数法坐标转换;探讨和研究了单点或批量处理坐标数据、输入或输出文件格式、参数解算及验证、坐标转换计算等问题,并对七参数坐标转换的结果进行了检验。
This article i rst analyzed the coordinate transformation method, and designed the transformation method of WGS84 coordinate system to national or local coordinate. Using Matlab software coordinate transformation programming, it achieved three ellipsoid earth coordinates and Cartesian coordinates, swap, and gauss projection and calculate, seven parameters calculating, seven parameters method of coordinate transformation between dif erent coordinate systems. At the same time, this paper discussed and researched single point coordinate data or batch processing, input or output i le format, coordinate transformation, calculation parameters and verification calculation and other problems, and checked the results of seven parameters of coordinate transformation. The operation interface is simple and beautiful, and the results of operation are reliable.
