摘要
基于XML标准的SVG是一种描述二维矢量图像的语言,对WebGIS的构建具备良好的可用性和适用性.提出了一个建立基于SVG的WebGIS系统的体系结构,将之应用于重庆大学校园电子地图系统中,证明了方案的可行性和实用性.对系统实现的关键技术进行了详细阐述:SVG空间数据组织编码方法;SVG电子地图的制作;SVG空间数据存储和系统客户端实现.
SVG based on XML is a kind of language describing 2D vector graphics. It is usability and applicability to set up WebGIS. The paper puts forward a system structure of WebGIS based on SVG, which has been applied to campus electronic map system of Chongqing University. It has been proved the method is feasibility and practicability. The paper sets forth some key techniques of implement of the system in detail : coding method of organizing SVG spatial data; generation of SVG electronic map; storage of SVG spatial data and implement of client.
