Seven-parameter coordinate conversion

The seven-parameter coordinate conversion is suitable for high-precision coordinate conversion in a large range between different coordinate systems (not the same ellipsoid) in Beijing 54 coordinate system, Xi'an 80 coordinate system, WGS84 coordinate system, and National 2000 coordinate system. At least three common points are required, and multiple common points are analyzed for accuracy, and the optimal and effective common point is automatically selected for conversion.
