摘要
本文分析了已有的关于地图符号库研究的不足之处,在此基础上,基于GIS库和图形库"两库合一"与"符号多重嵌套"思想,利用模板控制技术,采用程序设计和参数设计相结合的方式,对地图符号化模块进行设计,并实现了相关功能,对地图中的矢量目标数据(点、线、面、注记)进行静、动态符号化,实现SDE库中数据的符号化显示、符号化制图及符号化数据转换等功能。
This paper has been analyzed on the map-symbol for the inadequacy of the study,on the basis of the study,Base on GIS database and graphics database for the 'two for one' and 'symbol of multiple nested' thinking,using the template control technology,using procedures design and the design parameters of a combination of,on the map symbol of the module design and realization of the related functions:the map of the target vector data(point,line,surface,note),static and dynamic symbol of the realization of the SDE.The data showed that the symbols,signs and symbols of the mapping of data conversion,and other functions.
