水资源管理系统中最近资源点查找方法研究

The Implementation Method to Find the Closest Facility of Water Resources Management System

针对传统水资源管理系统在处理"查询一个位置点附近最短路径、指定数量的水资源元素"问题时的低效率、不直观、不精确的缺点,运用ArcGIS强大的地图显示与空间分析功能建立基于最短路径的最近资源点地图服务模型,并在Flex中调用、处理这个模型,实现在水资源管理系统中高效、精确、直观地显示某一位置点附近最近资源点的详细信息。

To solve inefficient, not intuitive, imprecise shortcomings of the water resources management system in dealing with the problem ＂Query a location near the shortest path, a specified number of water facility＂. Using the powerful map display and spatial analysis function of ArcGIS to establish the closest facilities service model based on the shortest path and Using the Flex calls, deal with the map service model. In the water management system to achieve efficient, aceurate, intuitive display detailed information of the closest facility.
