摘要
在分析地图符号本质特征基础上,将地图符号分为语义和图式两个相互联系的方面,并结合ISO/DIS19117图示表达规范,提出并设计了基于网络共享的图示表达模型,分析了地图符号的共享机制,为网络环境下地图符号的共享提供了可行的解决方案,为分布式地图符号化处理提供了理论依据.
Because there are different map symbols systems and interfaces in GIS softwares, between them the cartographic symbols cannot be shared. The essence of the cartographic symbol as a map language is discussed firstly; and we consider that the cartographic symbol includes the semantic expression and specifications portrayal. Then combining the ISO/DIS 19117, we develop the portrayal model based on network sharing, where the sharing mechanism of the cartographic symbols is analyzed. The model suggested provides a sharing method about the cartographic symbols in the internet, and provides a theory on distributed symbolization.
