介绍了一种在嵌入式设备上实现地图查询系统的可行方法。系统采用面向对象的程序思想进行设计,实现了对地图数据的基本操作等功能,还能够对符合不同查询条件的地图数据进行检索,利用网络图层的路经分析法,对出发点和目的地两点间最短路径进行分析、导航(模拟导航、真实导航)。关键词:嵌入式设备,地图查询系统,GIS,GPS,导航Abstract: This paper introduce a feasibility method of map query system in the embedded devices. It is designed with object-oriented technology and implemented by eVC and eSuperMap. It provides the many available functions including retrieving the map object information that fit specifical criterion, analyzing the shortest route between the start point and destination and navigation (simulation navigation, reality navigation).Keywords: embedded device, map query system, GIS, GPS, navigation
