| 摘 要： | 在GIS的模糊不确定性的条件下就模糊实体之间的拓扑关系进行讨论,在确定地理实体的拓扑关系的基础上,提出了模糊相交、模糊重合、模糊邻接、模糊包含等一系列的新概念,并针对模糊点、模糊线和模糊面之间的拓扑关系进行了具体分析。最后指出了模糊实体之间的拓扑关系存在的问题和今后的研究方向。

| Abstract: | The paper discusses GIS fuzzy entities topological relation in the case of GIS including fuzzy uncertainty, and brings forward a series of concepts such as fuzzy intersection , fuzzy identity , fuzzy adjoin and fuzzy inclusion on the foundation of certainty entities topological relation, and concretively analyses topological relation among fuzzy point, fuzzy curve and fuzzy surface. Finally the paper points out problems about fuzzy en- tities topological relation and the research issue in the future. |
