摘　　要：矢量地图数据缺陷识别规则是制图规范与细则的形式化描述,是矢量地图数据缺陷自动识别的基础。本文通过分析矢量地图数据缺陷的来源,抽象概括了缺陷识别规则,制定了缺陷识别规则库构建原则与表达形式。结合矢量地图数据特点与规则表达方式,从禁止关系规则、必须关系规则和其他规则三方面入手,将缺陷自动识别规则细分为范围控制规则、长度控制规则、关联推理规则等多种形式,并给出了规则的具体表达样例。Automatic identification rules for vector map data defect are the basis of automatic identification of vector map data defects and used to describe the cartographic specifications.By analyzing the sources of vector map data defect,the defect identification rules are summarized,and the principles and expressions of a defect identification rule database are formulated.Combining the characteristics and expression modes of vector map data,the defect automatic identification rules are constructed from aspects of prohibition relationship rules,must be relationship rules and other rules,and divided into scope control rules,length control rules and association rules.Expression samples of these rules are presented,which can provide theoretical basis for quality check of vector map data.
