针对传统WebGIS设计方法的局限性,利用Java平台无关性的优点,为拓展GIS在电子政务中的应用,提出了基于J2EE平台的Browser/Server模式的分布式解决方案,并以一个城市电子地图为例,着重探讨了J2EE平台上采用中间件(MapXtreme)设计和架构应用于电子政务的WebGIS的思想,主要包括客户端的选择、功能考虑以及服务器端的结构设计等,并据此提供了一个原型.该原型的建立及其设计的思想方法对于其他更为复杂的WebGIS的开发具有借鉴意义.After analyzing the localization of the traditional designing technologies in WebGIS,taking advantage of the platform-free characteristic of Java,for expanding the GIS applications in e-Government,this article provides an available distributed solution in Browser/Server model,based on J2EE platform.Taking an electronic map of city as an example,the article discussed the designing methods and configuration in WebGIS,which can be applied in e-Government,based on J2EE platform using middleware(MapXtreme),mainly including the choice of client,the designing consideration in client side and the structure designing in server side.According to that,the article provides a prototype.The prototype and the designing methods are helpful for other more complicated WebGIS.国家“九七三”信息与高性能软件的子项目(G199803040803)资
