基于ArcGIS Server与AJAX的WebGIS设计与实现

Design and implementation of WebGIS based on ArcGIS Server and AJAX

本文在AJAX理念的指导下,针对WebGIS的不足之处,设计与实现了城市交通矢量WebGIS原型系统。原型系统以ArcGIS Server WebADF框架为核心构建地图引擎,以AJAX开源引擎ExtJS作为前端辅助工具实现查询以及统计分析功能。试验表明,基于AJAX的富客户端WebGIS架构减轻了服务器端的负载,提升了客户端的运行效率,更加高效地提供了Web地理信息服务。

In this paper,under the guidance of AJAX concepts the design and implementation of urban transport vector WebGIS prototype system were introduced for the inadequacies of the WebGIS.The prototype system took ArcGIS Server WebADF framework as the core to construct the map engine,and realized query and statistical analysis function by using AJAX Open-source engine ExtJS as a front-end assistance tool.The experiment indicated that AJAX-based rich client-side WebGIS architecture could reduce the load on the server side,improve the operating efficiency of the client and provide Web Geographic Information Services more efficiently.
