| In many geographic applications there is a need to model spatial phenomena not simply by exact objects but rather through indeterminate or vague concepts. To support such applications we present a framework to model regions with indeterminate boundaries. The framework supports the modeling of the spatial, thematic and temporal dimensions of the spatial data as an integrated view for reasoning about vague regions. In spite of, the framework integrates spatial, thematic, and temporal reasoning, it focus on the spatial representation and reasoning. The novelty of our approach is in the definition of the concept of Fuzzy Minimum Bounding Rectangles. We have found this structure suitable to represent vague regions since these type of regions are fuzzy by nature. Thus, vague regions need a fuzzy representation to model the semantics of the phenomena classified in this category. |
