Description: GIS点状符号共享研究_陈泰生,分析了gis的3种典型符号模型不利于构建地图符号与符号间难以共享的原因,引入了pb符号模型,提出了符号数据共享与符号渲染功能共享相结合的符号共享机制,设计了3类gis点状符号与pb符号间的映射方法,实现gis点状符号共享,并利用实验对其进行了验证。-GIS point symbol Sharing _ Chen Taisheng analyzed gis three typical symbolic model is not conducive to building a map between symbols and symbols difficult to share the reasons for the introduction of pb symbolic model proposed symbol data sharing and shared symbol rendering capabilities combined symbol sharing mechanism designed three types of mapping methods gis point symbols and symbol pb between realized gis point symbol sharing, and use of experimental verification was carried out.

Description: 基于PB符号的图元类点状符号共享研究_陈泰生
针对不同平台间地图符号难以共享的问题,面向图元类点状符号,提 出一种基于PB符号的共享方法.从符号语法角度分析了图元类点状符号与基于路径的点状符号结构,对比了两类符号模型差异,探讨了PB点状符号结构的完备 性.利用PB点状符号模型,设计了图元类点状符号共享方法,从几何与样式两方面,提出了点类型、直线类型、弧段类型、光滑曲线类型以及组合类型图元的映射 方式.进而以SuperMap点状符号库为实验对象,构建了图元类点状符号共享实验,验证了该文所提图元类点状符号共享方法的可行性,将会促进GIS平台 间地图符号共享.
-Sharing point symbol primitive type PB symbol _ Chen Taisheng based platform for different map symbols difficult to share the problems facing the entity class point symbol, proposes a method based on shared PB symbols the point of view of grammar symbols element class point symbols and path-based point symbol structure, comparing the two types of symbolic model differences, we discuss the completeness PB dot symbol structure. PB use dot notation model, designed primitive class point symbol sharing method, geometry and style of both proposed point type, line type, the type of arc, smooth curve types and combinations of types of primitives are mapped. Further to SuperMap point symbol library as experimental subjects, constructed primitive class point shaped symbol sharing experiment to test the feasibility of the mentioned entity class point symbols sharing method, will promote inter-platform GIS map symbol sharing.
