摘要
用实例分析了应用平面四参数模型进行坐标转换时,不同坐标系的投影差异对坐标转换精度的影响,并对转换误差的原因进行了分析,得出了在利用平面直角坐标转换时必须保证各坐标系中央子午线应尽量一致的结论。
In this paper, application of plane model with four parameters are analyzed with examples of coordinate conversion of different coordinate system, the projection of different influence on precision of coordinate transformation, and the conversion error sources are analyzed, the use of plane rectangular coordinate transformation must ensure that each coordinate central meridian should be consistent.
