基于规则数据驱动的专题制图技术及其应用研究

地图制图自动化是地图学的重要目标之一,也是当前研究的热点问题之一,对地球空间信息科学的发展具有十分重要的意义。通过采用Representation技术,以昆明市入滇河道(管线)专题地图制图项目为例,研究探讨基于规则化数据驱动的计算机地图制图表达,部分解决了传统上必须通过大量人工编辑才能够完成的制图任务,特别是实现了传统上需要以破坏数据的GIS属性为代价才能够实现的地图制图效果,结果表明:基于规则驱动的计算机地图制图表达技术能够兼顾GIS和地图制图对数据的不同要求,可快速完成地图制作,并达到传统地图制图效果,节省大量的人力物力,具有广阔的推广和工程应用价值。

RULE-BASED DATA-DRIVEN THEMATIC MAPPING TECHNIQUE AND ITS APPLICATION RESEARCH

Cartography automation is one of the important goals to pursue by Map of Workers,and it is one of the hot issues of current research,It geospatial information science is of great significance.In this paper,Kunming,river（pipeline）into the Dianchi lake Thematic cartography project as an example,for the complexity of this project there is the map editor mapping workload and the need to achieve results,and quality requirements of the mapping data,the author uses Representation technology and secondary development based on the actual situation,study rule-based data-driven representation of computer cartography,the process must solve some of the traditional workload by a large number of human editors to complete the mapping task.In particular,realized the need to destroy some of the traditional GIS data attributes can be achieved at the cost effect of the map drawing.in cartography the results showed that：Rule-driven expression of a computer cartography and GIS technology can both map the different requirements for data mapping,map production can be completed quickly and achieve the effect of traditional cartography,can save a lot of manpower and material resources,has broad marketing and engineering applications.
