摘　　要：地图数据缺陷识别规则是缺陷自动识别的基础，影响着缺陷自动识别的查全率和查准率。本文对地图数据缺陷自动识别规则进行了系统的研究，论述了地图数据缺陷识别规则建立的依据；以空间关系冲突检测规则为例，分析了现有缺陷自动识别规则研究中存在的不足；研究了地图数据缺陷识别规则的表达形式和测试条件，提出了地图数据缺陷自动识别规则表达的五元组模型，并论述了该模型的特点；基于五元组模型建立了水系与等高线要素的空间关系缺陷识别规则。The defect identification rule of map data is the basis of automatic defect identification which affects the recall ratio and precision ratio of automatic defect identification. First this paper systematically studies the automatic identification rules of map data and states the basis of the rules construction. Then the paper analyzes the existing defect of automatic defect identification rules by taking the conflict checking rule of spatial relation as an example. Besides , the paper studies the presentation model and test conditions of rules, proposes quintuple model for automatic defect identification and describes the model characteristics. Finally it constructs the spatial relationship defects identification rules of water system and contour lines based on the quintuple model.
