Cover Story: This paper introduces conceptual neighborhood graphs for topological relations in discretized space (ℤ2), addressing a critical gap in qualitative spatial reasoning. Using simulation protocols, we derive comprehensive neighborhood structures for translation and isotropic scaling operations that capture topological transitions in pixel-based representations. Our findings reveal that these discrete neighborhood graphs maintain structural consistency with their continuous counterparts when appropriately aggregated. This framework enables crucial functionalities for modern spatial information systems—detecting temporal events, identifying missing state changes, enhancing query systems, and providing richer context for spatial prepositions—thereby advancing applications from cadastral analysis to remotely sensed data processing. View this paper
