摘　　要：矢量地图数据空间关系冲突是引起空间关系缺陷的主要原因之一，冲突缺陷的自动检测方法是矢量地图数据质量控制需要研究的重要内容。本文以矢量地图数据空间关系缺陷识别为目的，对矢量地图数据中线-面空间关系的集成表达模型进行了研究，提出了用于线-面空间关系缺陷识别的11种度量参数，总结归纳了线-面空间关系的基本类型，研究了组成复杂线-面空间关系的元拓扑关系、内外方向和连接顺序等要素，基于元拓扑关系，提出了线-面空间关系定性和定量集成表达模型。The spatial relationship conflict of vector map data is one of main reasons that lead to spatial relation defects. The automatic checking methods for conflicts and defects are important research contents in the field of vector map data quality control. In order to solve the spatial relation defect identification problem in vector map data, the integrated representation model of line- area relation is studied, and eleven measurement parameters to recognize line- area relation defects are proposed. Basic types of line - area relations are summarized, and the meta topology, the in and out direction and the connection order of complicated line - area spatial relations are concluded. Based on the meta topological relation, the qualitative and quantitative integrated representation model for line - area spatial relation arc put forward in this paper.
