空间数据库泛化是一项复杂的操作，不仅包括几何变换，还包括拓扑变换。这些更改通常会导致原始数据库和派生数据库之间的不一致。为了控制派生数据库的质量，必须对拓扑一致性进行评估。在本文中，我们提出了一套规则来评估拓扑一致性的坍缩操作。这些规则是基于折叠操作中拓扑属性的严格分类。通过这些规则，我们可以检测出泛化过程中不一致的拓扑变化，从而提高衍生数据库的质量。
Generalization of spatial databases consists of complicated operations including not only geometric transformations but also topological changes. The changes often result in an inconsistency between the original and derived databases. In order to control the quality of derived databases, we must assess the topological consistency. In this paper, we propose a set of rules to assess topological consistency for the collapse operation. The rules are based on a rigorous classification of topological properties in a collapse operation. By these rules, we can detect inconsistent topological changes in the generalization process and improve the quality of derived databases.
