摘　　要：本文首先阐述了北京54坐标转换至WGS-84坐标的意义,介绍了北京54坐标转换至WGS-84坐标的实现过程及其方法。最后通过计算江苏省北京54坐标数据和C级GPS网数据对两种坐标转换方法进行了比较分析,并得出了有益的结论。The paper illustrates the meaning of coordinate transformation from BJ54 coordinate system to WGS84 coordinate system. The specific methods and process of coordinate transformation are introduced. Finally, an analysis and contrast between two methods is given through calculating the data of BJ54 coordinate points and C-class GPS network. A good conclusion is drawn.
