基于REST和AJAX的WebGIS设计与实现

摘要

In order to overcome the problems existing in the traditional WebGIS,this paper designed and implemented the Fujian Transportation Geographical information releasing system under the concept of combining REST architecture style with AJAX technology.System depended on ArcGIS Server JavaScript API,through Extjs engine of AJAX to realize the function of querying map and statistics analysis,etc.The experiment indicated that WebGIS framework based on REST and AJAX reduced the load on the server side,also it could enhance the interactive ability between client and server side as well as improve the interoperability and flexibility of the system.%针对传统WebGIS技术存在的问题,提出REST架构风格与AJAX技术相结合的理念,设计并实现福建省交通地理信息发布系统.系统基于ArcGIS Server JavaScript API,并通过Extjs引擎实现地图的查询和统计分析等功能.结果表明基于REST与AJAX的WebGIS架构减轻了服务器端负载,增加客户端与服务器的交互能力,提高了系统的互操作性和伸缩性.
