Many geographical applications need to model spatial phenomena with vague or indeterminate boundaries and interiors. A popular paradigm adopted by the GIS community for this task at the modeling level is fuzzy set theory. A spatial object is fuzzy if locations exist that cannot be assigned completely to the object or to its complement. In previous work, the authors have proposed an abstract data model of fuzzy spatial data types for fuzzy points, fuzzy lines, and fuzzy regions to represent the indeterminacy of spatial data. This paper focuses on the problem of finding an appropriate implementation approach to fuzzy regions.
