同一地区不同来源地图数据库同名面实体的识别或匹配对空间数据库的集成与信息共享非常有意义。该文研究了城市地图数据库同名面实体匹配的有关问题 ,提出了基于模糊拓扑关系分类的面实体匹配方法 ,该方法充分考虑了源地图数据库的不确定性 ,能处理非一对一的匹配情况。匹配结果不仅可以作为城市地图数据库集成和信息共享的依据 ,还可以用来分析两个地图数据库之间的差异 ,进行变化检测与自动更新

This paper presents an idea to determinate the variant matching relationshinps among areal entities based on the overlay areas. Then a methodology to identify the counterpart elements based on the fuzzy classification of topological relationship is illustrated, which applies the concept of morphologic distance between areas introduced by Winter and the concept of fuzzy topological relationship theory. The resulted topological relationship between areas indicates the discre pancy between the considered areal features and also shows the degree of being or not being belonged to the identical features, which is important for further analysis or decision making. The methodology presented here enhances the technology of feature matching in the area of map conflation. Tests show that the method is well performed and has the ability to identify the non-one-to-one matching relationship and is well suited for areal feature matching among urban geographic databases with the same scales as well as similar scales.
