摘要
WebGIS是Internet技术与GIS相结合的产物,WebGIS为公众获取GIS数据和地理信息服务提供了一个有效的工具。但是目前许多WebGIS应用都依赖于GIS软件,由于GIS软件和数据格式多种多样,从而难以互操作,缺乏灵活性。本文以实现GIS在互联网上的传播为研究目的,探讨将SVG与GML结合应用于WebGIS的解决方案和应用模式,并详细分析了系统实现的体系结构和相关技术,着重论述了GML与SVG之间的转换方法。
WebGIS is the production of Intemet technology applying to GIS. WebGIS is a good tool to get GIS data and geographic information service for us. But now, many applications of WebGIS depend on GIS software, while it is difficult to deal with and is lack of flexibility because of diversity of GIS software and GIS data. This paper presented a kind of WebGIS using GML to organize and SVG to display geography data, thus the geography data could be displayed and transmitted on the internet, and the system architecture for realization and related technologies were analyzed in detail. The article focused on discussing conversion methods between GML and SVG.
