CGCS2000与独立坐标系转换模型适用性研究

摘要

For the transformation of China Geodetic Coordinate System 2000 and City Independent Coordinate System , how to select the appropriate transformation model is proposed by creating the coordinates with high precision or high compliance issues . The comparison method of side length and azimuth difference is used between the China Geodetic Coordinate System 2000 and Independent Coordinate System to analyze the transformation model features .And through the examples of common conversion model ,the applicability is tested and the different needs in coordinate transformation model selection are presented .This method has a certain reference for the other .%针对CGCS2000与城市独立坐标系转换中，如何根据需要选择合适转换模型，使产生的转换坐标具有高精度或者高符合性问题，利用CGCS2000与独立坐标系边长差和方位角差比较方法，分析转换模型特性。并通过实例对常用转换模型进行验证，归纳出模型的适用性，解决坐标转换中不同需求模型选择问题。文中方法对其它坐标转换有一定借鉴作用。
