Abstract: Spatial similarity relation is widely used in description and matching of spatial objects, retrieval and renewal of spatial databases, and spatial recognition and spatial reasoning. However, there exist only few trivial achievements in spatial similarity relations, for spatial similarity relations are usually comprehensive and complex, and they cannot be described and expressed formally and cannot be calculated conveniently, either. Therefore no theoretical system of spatial similarity relations has been constructed by far. To fill the gap, this paper proposes a theoretical system for spatial similarity relations. Based on the system, this paper firstly presents the definition, classification systems, features and influence factors of spatial similarity relations, and then addresses the calculation methods of spatial similarity relations at the same scale space and different scale spaces, respectively. Further, it presents some applications of spatial similarity relations. Finally, it gives a number of potential research issues in spatial similarity relations. This work is a useful complementary of the theory of spatial relations and possibly makes the research in spatial similarity relations more rigorous, deeper and more systematic in future.

Key words: theoretical system, spatial similarity relation, spatial relation, same scale, multi-scale
