VC环境下基于GIS的GPS导航系统的开发

Development of GPS Navigation System Based on GIS in VisualC

从空间定位技术出发 ,在VC 环境下 ,以MapX控件为图形平台 ,以MSComm控件为通信平台 ,开发具有属性查询、空间分析等GIS基本功能的GPS导航信息系统。

The paper discusses on the basis of spatial position technology in VC how to develop GPS navigation system by using MapX control as a graphics tool and MSComm control as a communication tool ,and accomplish the basic GISfunction of analyzing and querying the spatial data and attributive data.
