摘要：Topological predicates on spatial objects have been a main area of research in spatial data handling, reasoning, and query languages. The focus of research, has, to a large extent, been on the design o f and reasoning with these predicates, whereas implementation issues have been somewhat neglected. The goal of this paper is to show ho w an abstract design of topological predicates for complex regions can be efficiently implemented. The resulting algorithms are based on the realm concept, which is well known in the spatial database community
