This paper presents a quantitative analysis model for indeterminate topological relations between uncertain spatial *** model use Grey set to represent uncertain spatial regions,which have a pair of membership function instead a single one to describe the indeterminacy *** the cut-set operation on the Grey set,uncertain spatial regions can be turned into crisp region *** applying relative qualitative topological analysis model such as the Egg/Yolk model on these crisp region pairs,the indeterminacy of topological relations can be quantified to a probability range.
