摘　　要：在GPS定位应用中需要将GPS接收到的定位数据在电子地图中实时显示。介绍了WGS-84坐标系与北京-54坐标系之间的坐标转换过程以及七参数转换模型的参数求解方法。基于ArcGIS Engine嵌入式开发组件提供的IGeometry接口的Project方法,结合VisuaI C#开发语言、Visual Studio 2008开发环境设计开发了GPS定位显示系统。实际应用中,系统较好地满足了GPS定位中坐标转换精度的需求,具有较好地适应性和快捷性。In GPS positioning applications,we need to display the location data received by GPS equipment on the electronic map in real time.This article describes the coordinates of the conversion process between the WGS-84 coordinate system and the Beijing-54 coordinate system and the seven-parameter transformation model parameters solution method.Based on the method of Project of IGeometry interface of the ArcGIS Engine Embedded development components and combining VisuaI C# and Visual Studio 2008,we develop the GPS positioning system with good adaptation and convenience,which meets the conversion precision requirements in practical uses.
