摘要
针对目前专题地图编制要求作业人员具备专业知识进行大量的地理数据、专题统计数据处理和繁琐的专题图设计导致生产效率低下的问题,本文通过研究专题地图编制流程,总结了地图设计过程中的内容设计、版式设计、符号色彩设计、整饰设计等知识体系,并将地图设计流程结构化、模型化,用信息化的语言存储地图设计的各个过程,构建地图设计的知识规则库,然后基于地理要素和专题要素符号化机制构建制图模型,最后结合上述方法采用计算机编程技术研发了专题地图一体化编制系统,并运用系统进行试验样图编制。结果表明本文方法可提升专题图制图效率,为专题地图生产编制提供了有力的技术支撑。
According to the fact that thematic map compilation needs staff owing professional knowledge to process large amounts of geographic data and thematic statistical data and leads to low production efficiency of thematic map design,this paper studies thematic map compilation process and summarizes knowledge system of map content design,layout design,color design,map symbols and decoration design.Then map design process is structured,modeled and stored using information language to construct knowledge rule database.Cartographic model is constructed based on symbolization mechanism of geographic and thematic features. Finally,based on the above method,thematic map integration system is developed using computer programming technology and sample map is compiled using the system.The results show that the paper＇s methods can improve the efficiency of thematic mapping,and provide powerful technical support for the production of thematic maps.
