摘要
本文在分析二维相似变换模型的基础上,提出了一种适用于工程GPS网基准点兼容性分析的"较差阈值法",给出了较差阈值的确定方法,构建了相应的程序模块,利用工程实例证明了该方法的有效性和正确性。
Based on the analysis of the two dimensional similarity transformation model, the paper puts forward a compatibility analysis method named ＂ difference threshold method＂ , which is suitable for point coordinates used as engineering GPS network datum. A method to calculate the difference threshold is given and corresponding program modules are implemented. Finally, the feasibility and effectiveness of this method are proven by an engineering example.
