基于ArcGIS Mobile的最短路径分析方法研究

Shortest Path Analysis Method Using ArcGIS Mobile

在移动设备上实现道路最短路径分析的方法很多,在研究了各种方法后,本文综合利用ESRI(Environmental Systems Research Institute,Inc.美国环境系统研究所公司)提供的ArcGIS平台,提出了在移动设备上实现最短路径分析的一种新方法.首先,在C#.NET语言开发平台下,使用ArcGIS Engine嵌入式地理信息系统接口开发技术,开发路径分析的整体过程,并把该过程做成Dll功能组件;然后,把该功能组件发布成WebService,最后,移动设备通过GPRS无线网络调用该服务所返回的结果字符串,实现最短路径的分析.

There are many ways to achieve the shortest path analysis of the road in mobile devices.After study a variety of methods,it will comprehensive utilization ESRI（Environmental Systems Research Institute,Inc.U.S）which provide the ArcGIS platform,achieve a new approach to the shortest path analysis in the mobile devices.First,using ArcGIS Engine embedded interface development techniques in C#.NET language development platform,to develop path analysis of the overall process,and made the process to Dll functional components;then released the functional components into WebService,finally,the service is called by mobile devices via GPRS wireless network to achieve the shortest path analysis.
