J 2EE 平台WebGIS 设计技术探讨

Abstract

针对传统WebGIS 设计方法的局限性,利用J ava 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(MapXt reme) 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. [英文摘要]Af ter analyzing the localization of the t raditional designing technologies in WebGIS ,taking advantage of the platform2 f ree characteristic of J ava ,for expanding the GIS applications in e2Government ,this article provides an available dist ributed solution in Browser/ Server model ,based on J2EE platform. Taking an elect ronic map of city as an example ,the article discussed the designing methods and configuration in WebGIS ,which can be applied in e2Government , based on J2EE platform using middleware (MapX2 t reme) ,mainly including the choice of client ,the designing consideration in client side and the st ructure designing in server side. Ac2 cording to that ,the article provides a prototype. The prototype and the designing methods are helpful for other more complicated WebGIS.
