摘 要: | 根据信息时代地图产品的多种可视化格式输出要求,针对现有地图制图与出版软件的不足,论述了支持多种格式输出的地图符号库的研究内容。在分析地图符号库与多格式输出技术的基础上,提出了多格式输出地图符号库的设计思路。利用该符号库可以实现使用一套符号库,根据地图的不同可视化目的,既能输出用于屏幕显示的GDI 格式,又能输出制版印刷的EPS/PDF格式、网络分发传输的PDF格式和网上交互操作的SVG格式。克服了当前地图制图与出版软件在多格式输出方面的不足。

Abstract: | To meet the demands of multi-format outputting of map and weakness of existing cartography and publish softs,the article discussed the research content of map symbol library which supporting multi-format outputting.With analyzing the technology of map symbol library and multi-format outputting,the authors put forward the design thought about map symbol library which supporting multi-format outputting.Using this map library,the system could output various format included GDI format for displaying on screen,EPS/PDF format for printing,PDF for distributing on network and SVG format for alternation on network. |
