摘要
GML作为一种空间信息的编码、存储和交换格式,已逐渐被接受并广泛使用,为实现空间信息的共享和WebGIS的进一步发展提供了一个强有力的工具;SVG作为一种网络时代的图形文件格式标准,综合了矢量图形、位图图像和纯文本的优点,对网络环境有天然的适应性,代表未来网上图形传输发展的方向,因此,基于GML&SVG的WebGIS研究与应用具有广泛的实用价值和应用前景。文中提出了利用GML进行地理信息的存储和集成,并用SVG实现地理信息的Web显示,操作的开放式WebGIS体系结构和解决方案。且在此基础上,建立了GML&SVG的WebGIS应用系统。
GML(Geographic Markup Language) is gradually accepted and widely used as an encoding,storage and exchange format for spatial information,and it offers a powful tool for implementing spatial information sharing and WebGIS development. As a graphic file format standard in the network era,SVG(Scalable Vector Graphic) represents graphic transmission development direction on the web,which integrates vector graphic,bitmap image and plain text merits and is naturally compatible with the network environment,so study on GML and SVG-based WebGIS and its application will have extensive practicality and application value. In this paper,GML and SVG are discussed firstly,especially in the role of open WebGIS,then an open WebGIS architecture is put forward which uses GML to store and integrate geographic information and using SVG to implement web display and operation for geographic information. Finally,taking a campus map issuing system as an example,an open WebGIS application system is set up and discussed.
