摘要
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,并基于模板跨平台实现相关功能,对空间数据(点、线、面、注记)进行静、动态符号化,实现空间数据符号化显示、数据转换等功能。
The paper analyzes the map-symbol for the inadequacy 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 to design and realize 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 can be realized.
