摘要：Fuzzy spatial objects have become more and more important in GIS applications. When spatial phenomena are generalized by the crisp form, a lot of quantitative information is lost. Land cover as a fuzzy spatio-temporal object should be modeled in a fuzzy framework. In addition, topological relations between fuzzy spatial objects are much more complicated than that are defined between crisp spatial objects. The purpose of this paper is to construct topological relationships; as one of the most important characteristics of spatio-temporal objects; based on fuzzy logic with its applications to land cover. An area in Tehran which has lots of land cover types was considered and topological relationships between them were constructed both spatially and temporally
