Two vital shortcomings of existed topological relation models for indeterminate topological relation description are summarized firstly. In order to get them over, a novel topological relation model for indeterminate geographical object is constructed based on fuzzy Close-degree analysis, where the five familiar topological relation predicates of RCC5 are adopted as the basic topological relation set. Then the workflow of computation of fuzzy topological relation is worked out. In the end a case study is implemented, and the results illustrated that the model is reasonable and viable.
