本文从平面坐标转换方法出发，推到了平差中各转换模型的设计矩阵，最后结合CGridCtrl表格控件开发了平面坐标转换应用程序，可以大大提高了工程中坐标转换计算的效率。-This departure from the plane coordinate conversion method, pushed to the adjustment in the conversion model design matrix, and finally developed with CGridCtrl form control plane coordinate conversion applications, can greatly improve the engineering efficiency of coordinate conversion calculations.
