摘要
地图符号的选择在空间信息可视化中至关重要。本文基于案例推理的研究范式和专题制图过程,提出了一种智能化专题制图的CBR框架,它依赖的知识主要是系统所存储的专题地图设计过程中解决问题的具体记录。本文从案例库内容设计、案例表达和数据库模式、案例相似性计算和案例检索等方面重点研究了CBR在统计地图表示方法智能选取中的应用,并以《中国人口地图集》为蓝本,以myCBR为工具,展现了CBR在专题地图设计知识获取、表达和推理中的应用潜力。
Selection of map symbols is very important in visualization of spatial data.An intelligent thematic mapping framework based on research paradigm of case-based reasoning and thematic mapping process is proposed in this paper.The knowledge depended is the concrete problem solving records during designing of thematic maps which are stored in the CBR system.Intelligent selection of representation method for statistic maps is explored in different aspects from content design of case base,case representation,database schema,similarity measure and retrieval of cases.Based on ＂Chinese Atlas of Population＂ and myCBR tool,experiment is designed and shows the potential of CBR in the acquisition,representation and reasoning for thematic mapping.
