For a long time topological relationships between spatial objects have been a main focus of research on spatial data handling and reasoning. They have especially been integrated into query languages of spatial database systems and geographical information systems. One of their fundamental features is that they operate on spatial objects with precisely defined, sharp boundaries. But in many geometric and geographic applications there is a need to model spatial phenomena and their topological relationships rather through vague or fuzzy concepts due to indeterminate boundaries. This paper presents a model of fuzzy regions and focuses on the definition of topological predicates between them.
