Abstract: Through analyzing the problem of the present map symbol sharing technology in GIS,a sharing method of map symbol in GIS based on Symbol Encoding complementation(SE) is put forward.Common map symbol system,including SE symbol data models,symbol editors and symbol draw engine,will transform international map symbol standards into a practical map symbol sharing method.And with the method,when sharing the geographic spatial data,can realize the sharing of the same map symbol library both in various GIS software and on the Internet.

摘要: 从分析现有GIS地图符号共享技术及其存在的问题入手,提出了一种基于OGC符号编码规范(SE)的GIS地图符号共享方法。由SE符号数据模型、SE地图符号编辑器和地图符号绘制引擎形成的通用地图符号系统将理论上的国际地图符号规范转变成具有可操作性的GIS地图符号共享方法,使人们在共享地理空间数据的同时,实现同一地图符号库在多个GIS软件之间以及在Internet环境下的共享。
