| 摘 要： | 随着空间数据库应用的推广，对空间数据挖掘的探讨越来越深入。作为必要前提的空间目标拓扑关系的建立也成为急需扩展的方向。但是目前讨论的大多数方法并不考虑空间信息的不确定性。这里针对具有宽广边界的目标，介绍一种9-交集矩阵，并对其进行扩展，完善了对具有宽广边界目标建立拓扑关系的方法。

| Abstract: | With the extension of applying spatial database, the discussion of mining the spatial database is becoming further and further. As the indispensable premise, setting up the topological relations of spatial objects also need to expand. However, the majority methods discussed at present do not consider the undetermined character of spatial information. Here, a method for the objects witha broad boundaryis introduced, which is called9-intersection matrices. What's more, thismethod isextended to modify the method of setting up the topological relation for objects with a broad boundary. |
