摘要: 为能在移动设备资源限制的情况下提供高效高质的地理信息系统(GIS)服务,分析研究移动GIS引擎的系统体系结构和类库结构。采用A*算法解决移动GIS最优(短)路径搜索的问题。通过对引擎内部层次结构的设计,结合手机GPS定位和电子地图等关键技术,在Windows 移动平台上用VC++语言开发并实现一个移动GIS引擎系统。研究结果表明该引擎系统界面整洁,功能良好,且A*算法的搜索效率提高15%~20%。

Abstract: How to provide high quality Geographic Information System(GIS) services under resource constraints on mobile devices, the system architecture and structure of a mobile GIS engine is analysed and designed. Using the A* algorithm to solve the problem of searching for optimal/shortest path in GIS. Through achieving an internal hierarchy of the engine, combining with position of mobile GPS and digital map technology, a mobile GIS engine system is achieved based on the Windows mobile platform using VC++. Studies show that the engine system interface is clean, well-functioning, and the search efficiency of A* algorithm is increased by 15%~20%.

Key words: mobile Geographic Information System(GIS), search for optimal(shortest) path, A* algorithm, Windows mobile platform, engine system
