This paper revisits conceptual neighborhood graphs for the topological relations between two regions, in order to bridge from the A-B-C neighborhoods defined for interval relations in R

to region relations in R

and on the sphere S

. A categorization of deformation types—built from

and
different
positions, orientations, sizes, and shapes—gives rise to four different neighborhood graphs. They include transitions that are constrained by the regions’ geometry, yielding some directed, not undirected neighborhood graphs. Two of the four neighborhood graphs correspond to type B and C. The lattice of conceptual neighborhood graphs captures the relationships among the graphs, showing completeness under union and intersection.
