【摘要】 南水北调中线工程是我国最大的调水工程,其干线工程沿线建筑物众多,运行工况复杂。开发南水北调中线干线工程WebGIS系统能够作为工程调度运行的管理平台,提高系统运行调度的信息管理水平。此外,该系统可在Internet发布工程地图信息,供社会公众浏览、查询,更好地为社会经济服务。介绍了南水北调中线干线工程的WebGIS系统,该系统是根据南水北调中线工程的特点采用Java为语言和Ajax技术以服务器动态缓存地图的形式开发的。南水北调中线干线工程WebGIS系统以ArcIMS9.2作为地图引擎,Oracle10g为数据库管理软件,Tomcat5.0Web服务器。由于开发过程中采用了地图瓦片存储技术,客户端在浏览的时候直接加载生成好的地图图片,从而提高了浏览速度,也减轻了服务器的负荷。更多还原

【Abstract】 The Middle Route of South-to-North Water Diversion Project,with many buildings and being operated under complex conditions,is the largest water diversion project in China. Developing WebGIS for this project can not only provide a platform for operation and management and improve the information management,but also provide project map on the Internet to the public for browsing and inquiry. A WebGIS system is introduced,which developed by Java language,and the map of the project is presented by Ajax technology in the form of server dynamic buffer map. ArcIMS9.2 is used as map engine,Oracle10g as database management tool,and Tomcat5.0 as web server software. A key technology,map tiles technology,is used in this system. Since the map tiles of the project are generated previously in the server,the clients can browse the map of the project quickly.更多还原
