摘要: 研究了模糊地理对象建模的空间建模方法,首先以对象建模方法定义模糊地理对象,以矢量数据模型为基础,用UML设计模糊对象类和模糊地理对象类,然后以统一的UML图表示基本模糊地理对象的概念模型,尤其是模糊拓扑关系,最后将UML图直接导入通用关系数据库,完成数据库的设计。

Abstract: The methods of spatial modeling for fuzzy geographical objects are focused and the following two issues are resolved.Firstly,fuzzy geographical object is defined by the novel object-oriented modeling method.Secondly,fuzzy object class and fuzzy geographical object class are defined by unified modeling language(UML) based on vector data model,and the method of modeling spatial relationship is put forward.Then an integrated UML graph is established to express the conceptual model of fuzzy geographical object as well as the fuzzy topological relationships between objects.Last,the UML graph can be input to the general relation database to finish the database design.
