基于SVG的地图符号库设计

Design of Cartographic Symbol Bank Based on SVG

地图符号的设计与实现是计算机地图制图领域研究的基本问题,而地图符号的共享则是WebGis研究的重要内容。把地图符号设计的基本方法与开放标准的二维矢量标记语言SVG相结合,设计了基于SVG的地图符号,提高地图符号的规范化、标准化、共享性。通过基于SVG的地理信息发布,结果证实能够满足我国地形图图式规范的符号表达要求。

Design and realization of map symbol is the basic research in compute aiding drawing map, but share of map symbol in internet is the main aspects in research of WebGIS. Combining the basic method of designing map symbol and SVG, this paper designed the map symbol bank based on SVG. By doing a number of experiments, the map symbol bank we designed can satisfy the need of drawing map application in China.
