Research on the Coordinate Transformation Methods between National System and Local Independent System

摘要：

The coordinate transformation between national system and local independent coordinate system is an important problem in geodesy and geomatics work. The similar transformation method and polynomial approximation method in coordinate transformation were discussed in this paper; the results indicated that the precision of polynomial approximation method was better than similar transformation method in big city.
