一种实用的GPS/电子地图坐标转换算法

The study on GPS/digital map coordinate transformation

    摘要
  • 摘要: 在GPS车辆定位导航系统中,需将GPS接收到的定位数据在电子地图中实时地显示出来.GPS定位数据属于WGS-8坐标系,而电子地图坐标系系5北京坐标系的高斯平面投影.本文详细讨论了几种坐标系之间的坐标转换问题,并给出了具体算法,将GPS数据转换为电子地图所需的数据形式,并进行了跑车试验,结果表明,该算法实用有效.

     

    Abstract: In vehicle location and navigation system with GPS,It is necessary that GPS data be displayed on the digital map in real time.GPS data belong to WGS-84 coordinate and the digital map coordinate is guass plane projection of 54'Beijing coordinate. The paper discusses the transformation problem between different types of coordinate systems, and simulates an algorithm to convert GPS data into a data form that can be displayed on the digital map. The result shows that the algorithm is practical and valid.
