| Abstract: | Changing the parameter of the National Geodetic Datum Reference Ellipsoid,regarding the new ellipsoid as projection datum,choosing an appropriate central meridian,and by the way of similitude transforming,the Xi'an 1980 National Coordinate System can be transformed into A City Local Independent Coordinate System.The interior according precision and the exterior according precision of the transformation is also compared and analyzed. |
