| 摘 要： | 地理置标语言GML是一种基于XML的编码语言,用于地理及地理相关信息的建模、传输和存储。本文首先对GML的发展历程作了概要说明,描述了GML文件的组成及其中的系统默认样式模式(defaultStyle.xsd)。利用现有的GML元素定义了地图注记的基本要素,形成了地图注记模式,最后实现了基于GML的地图注记表达。

| Abstract: | Geography Markup Language(GML) is an encode language based on XML grammar.It is used for modeling,transport,and storage of geographic information.In this paper,firstly the development course and current situation of GML is briefly summarized.The composition of GML document and its default style schema are described.The basic elements of cartographic annotation are defined using the existing GML elements,the schema of cartographic annotation is created and the results is represented based on GML. |
