摘　　要：开放共享是地理信息应用的重要研究方向,是实现陆海空地理信息融合的有效方式之一,是地理信息进一步融入信息行业的重要趋势。对于地理空间数据的开放共享已经得到普遍认可,但是对于地图符号的共享却未得到应有的重视,也未形成统一认识。本文对四个适合于地图符号共享的成像模型(Post Script、HPGL、True Type和SVG)进行了梳理总结,分析比较了各自的优缺点,认为SVG可作为陆海空地图符号统一的基础。Open sharing is one of the main trends of geographic information application.lt is the prerequisite for the integration of land,sea and air, and it is the only way for the further integration of geographic information into the infomation industry.The open sharing of geospatial data has been widely recognized,but the sharing of map symbols has not been paid enough attention to, and there is no unified understanding.In this paper, four imaging models（PostScript,HPGL,TraeType and SVG） suitable for map symbol sharing are summarized,and their advantages and disadvantages are analyzed and compared.lt is considered that SVG can be used as the basis for the unification of land, sea and air map symbols.
