| Abstract: | 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 . |
