摘要
得出了GPS坐标(WGS-84坐标系)到电子地图坐标(54北京坐标系)的转换算法,同时根据实际系统的要求,在保证精度的情况下,得出了简化的坐标转换公式,并把两种算法结果进行了比较.实际表明,得出的简化算法可行。
The transformation algorithm from GPS coordinate (WGSS 84 coordinate) to Digital Road Map Coordinate is presented.At the same time the simplified transformation algorithm is also proposed.The results of comparison betweem two kind of algorithms show that the simplified algorithm is usdful and its accuracy is suited to the need of appilcations.
