摘要
GPS输出数据是WGS-84坐标系,我国地图使用北京-54或西安-80坐标系,以不同的坐标系的数据进行匹配,会造成较大误差.为减少误差,提供WGS-84坐标系与西安-80坐标系的变换公式,并介绍其在车辆定位监控系统中的应用.
The GPS output data accords with WGS- 84 coordinate,but in China maps Beijing - 54 or Xi＇an 80 coordinate is used. To match the data from different coordinate,big error will be caused. Formula is provided for conversion between the data WGS- 84 coordinate and Xi＇ an - 80 coordinate. Its application in vehcile orientation and monitoring system are introduced too.
