Abstract :
In this contribution a representation of imperfect spatial information is proposed based on linguistic qualifiers within fuzzy set theory and possibility theory. By adopting a fuzzy object oriented database approach new data types for representing geographic entities characterized by either unsharp boundaries or indeterminate boundaries and relationships are defined. Finally, the evaluation mechanism of vague topological constraints between fuzzy and indeterminate spatial objects is described
