摘要:Uncertainty modeling for geometric data is currently an important problem in spatial reasoning, geographic information systems (GIS) and spatial databases. In many geographical applications spatial regions do not always have homogeneous interiors and sharply defined boundaries but frequently their interiors and boundaries are fuzzy. This paper provides a fuzzy spatial region model based on flou set. The model is different from the original fuzzy model that uses membership value but makes use of the relative relations between point sets, and represents a fuzzy region as a flou set. The model can obtain the properties and relations of fuzzy regions by using the operational properties of flou set. The fuzzy region model based on flou set is valuable in the fields such as GIS, geography and spatial database
