摘要
通过对WebGIS的三种处理模型的分析,根据GIS系统的特点,提出了用XML实现三层网络结构的WebGIS系统模型。该模型具有减少网络流量、更有利于检索、可从多种不同的数据源集成数据、开放性、可扩充性、可重用性等特点。
The paper, simply analyzing three models of WebGIS and characters of GIS, puts forward a WebGIS model based on 3-tiered net framework by XML. The model has so many advantages as reducing network flows, easily retrieving, integrating data from many different data sources, opening, extending and replicating.
