SVG技术在网络地理信息系统中的应用

Analysis of SVG technology applications in WebGIS

网络地理信息系统目前面临着W eb语言不支持矢量图形、传输种类繁多的海量空间数据受网络带宽以及其它路由限制等一些技术难关,本文针对地理信息系统遇到的这些问题,通过分析研究SVG技术及其优势,将SVG技术引入到W ebGIS,提出并分析了基于W ebGIS的系统架构及工作原理,可以看出,W ebGIS中应用SVG技术具有良好的发展前景。

The network geographical information system faces some difficulties that the Web language does not support vector graphics . Thus delivering a great deal of variety spatial data is limited by the network bandwidth currently etc. Aimed at solving these problems in the geography information system, this paper analyse SVG technique and its advantages, puts forward system structure and work principle of WebGIS based on SVG technique. In this way, application of SVG technique has the good development foreground in WebGIS.
