Fuzzy Geographical Object Modeling Based on Vector Data Model

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.
