摘要
SVG具有适合网络发布的优点,其应用于地图网络传输与发布,既能解决目前地图网络发布面临的难点问题,又能增强基于网络的地图应用功能。分析了SVG应用于空间数据可视化的优势,地理空间数据在SVG文档中如何进行数据组织及编码,实现GML数据到SVG数据的转换、SVG地图的显示与网络交互,提出了基于SVG的地图网络发布模型。
The preponderance of SVG is suitable to publishing information in the internet, which can not only solve the problems of current maps web publishing, but also strengthen the functions of map web application. The preponderance of SVG in spatial data visualization is analyzed and how to process spatial data organization and encode based on SVG is stud- ied. The diversion from GML data to SVG and displaying and operating the SVG map is realized. A model of map web publishing on SVG is given.
