Transformation Program and Precision Analysis between Geodetic Coordinate and Gauss Plane Coordinate

The paper gained formula that adopted computer computation based analyzing transformation formula between geodetic coordinate and Gauss plane coordinate.It adopted method that programs many subprogram and realized transformation between geodetic coordinate and Gauss plane coordinate,programs to realize transformation Beijing 54 coordinate,Xi'an 1980 coordinate,30 band Gauss plane coordinate and 60 band Gauss plane coordinate.The paper analyzed precision about transformation results,drew a conclusion that it can meet ordinary production use adapting the transformation program,but there was a little error.
