A Method of Plane Datum Transformation by Coordinate Parameterization

  • The mutual transformation of coordinates in different coordinate systems is a very common geoprocessing task. High-accuracy transformation parameters are the foundation for coordinate transformations, obtained by similarity transformations. Traditional least squares similarity transformation only considers common point coordinates in one coordinate system, and does not conform to many practical situations. Because common points have errors in two coordinate systems, the G-M model is not correct. The coordinates parameterization least squares, method overcomes this problem. Based on the principle of similar transformation, the traditional least squares method is used to calculate plane datum transformation parameters.
