3D Four Parameters Coordinate Transformation Model for Map

    Abstract
  • China Geodetic Coordinate System 2000(CGCS2000) was formally released to be used in China on July 1 in 2008.So all products related to reference ellipsoid should be transferred to CGCS2000.We main discuss how to transfer maps from reference coordinate system to CGCS2000 with 3D four parameter coordinate transformation model.In order to test the proposed method,the experimental areas which could stand for characters of whole country were chosen.Computation and analysis show that the recommended method can fully meet the accuracy of basic scale map transformation in China,and is better than the existed methods while it is simple and convenient.
