Topological relations are sometimes insufficient for differentiating spatial configurations of two objects with critical difference in their connection styles. In this paper, we present the projective 9 ∈+∈ -intersection model, which refines topological relations into projective binary relations by considering projective properties of the objects' shapes. This is indeed a reformulation of projective concepts of the Dimensional Model within the framework of the 9 ∈+∈ -intersection. Thirty projective binary relationsare established between two regions in R 2, one of which has a multi-order boundary (region ∈+∈mob). These relations are identified computationally by applying to all theoretical relations the existing constraints for topological region-region relations and seven new specific constraints. After defining the concept of continuous neighbours between two projective binary relations, a conceptual neighbourhood graph of the 30 projective region ∈+∈mob-region relations is developed. © 2008 Springer-Verlag Berlin Heidelberg.
