Abstract
通过分析目前矢量符号库的优缺点，对SVG矢量点符号库的符号制作，上传与存储，检索、抽稀与显示到地图进行了详细讨论，并结合WebGIS平台软件ECNUGIS的制图应用，为Web端矢量符号库的设计与实现提供了新的思路和方法。 Through analyzing the advantages and disadvantages of the current vector symbol database, the symbol production, upload and storage, retrieval, extraction and display of SVG vector point symbol database are discussed in detail. The new idea and method are given in the design and imple-mentation of vector symbol database for Web, which has been used in mapping application of WebGIS platform—ECNUGIS with good practical effects.
