新型专题地图制图自动化系统框架与关键技术

The framework and key technologies of a new automatic thematic mapping system

针对信息技术和行业需求对专题地图制图的表达内容、表达方法、表达形式和智能化水平带来的巨大冲击问题,通过总结和分析可视化技术和专题地图制图技术的发展,提出了一种新型专题地图自动化制图方法,设计实现了专题地图制图自动化框架。通过对空间数据无缝转换、专题应用模型库构建、开放式制图规则库与符号库设计、注记与符号自动配置、制图要素关系自动处理、地图整饰自动化等关键自动化技术进行研究,基于底层核心制图引擎和内嵌式插件开发技术,研发了专题地图自动制图系统,实现了空间数据库和应用模型驱动的专题地图制图流程。以多种专题地图制图实例进行了验证,结果表明系统较好地满足了多场景的专题制图需求。

In view of the great impact of information technology and industry needs on the content,method,form and intelligence level of thematic mapping.By summarizing and analyzing the development of visualization technology and thematic mapping technology,a new automatic thematic mapping method was proposed,and the automatic thematic mapping framework was designed and realized.Based on the research of key automation technologies such as seamless transformation of spatial data,construction of thematic application model base,design of open cartographic rule and symbol base,automatic configuration of annotation and symbols,automatic processing of cartographic element relationships,and automatic map decoration,an automatic thematic mapping system is developed.The system realized through the underlying core mapping engine and embedded plug-in development technology,which implemented the thematic map mapping process driven by spatial database and application model.A variety of thematic map mapping examples are used to verify the system,and the results show that the system can well meet the needs of thematic mapping in multiple scenarios.
