基于SVG的网络地图预览模型的设计和实现

Design and Realization of Web Map Preview Model Based on SVG

主要设计了应用于地理数据网络发布中的地图预览模型结构,利用SVG技术中数据量小、可缩放、可连接的特点和元数据描述作用,实现了基于SVG的地图预览模型,并提供相应地理空间数据信息查询,该模型适用于地理空间数据图形的在线浏览,以及复杂地理空间数据的在线图形预览。

This paper mainly designed the structure of map preview model for geographical data web publishing. It realized the map preview model based on SVG using the characters of small data amount, scalable, linkable and the metadata description function in SVG technology. The model provides relevant geospatial data information inquiry and is suitable for online browsing of geospatial data graphics and online graphics preview of complex geospatial data.
