Description: This procedure is used to WGS-84 coordinate system to the Beijing 1954 conversion. Need to convert at least three control points. These control points should be known in WGS-84 and Beijing 1954, three-dimensional Cartesian coordinate system of space coordinates. Procedure solver to calculate the conversion parameters solver. Conversion parameters obtained after the conversion process through the calculation of parameters to be turning point in Beijing in 1954, the space coordinate system cartesian coordinates.
