【摘要】 随着地图知识的不断积累以及地理数据在Internet中应用范围的不断扩大,越来越多的地图知识需要表达出来。XSL是一种基于XML的可扩展样式表语言,用于不同XML文档之间的相互转换。本文利用XSL表达地图知识,将地理标记语言GML转换为SVG,实现GML的符号化,完成GML的地图表达。并在实验基础上,分析了该方法的原理与优点。更多还原

【Abstract】 With the accumulation of map knowledge and the expanse of spatial data’s application in the Internet,more and more map knowledge based on location needs to be represented.Extensible Stylesheet Language(XSL) is a language based on XML,which can transform one XML documents to other XML documents.This paper uses XLS to express map knowledge.It transforms Geography Markup Language(GML) to SVG,then to realize the symbolized GML and perform the map representation of GML.On the basis of experiment,the paper analyses the principle and merit of this method.更多还原
