Abstract: A framework for the description of 2-D topological spatial relationship is presented, and the smallest set of 2-D topological spatial relationship is defined, which consists of six types of topological spatial relationship. The completeness and mutual exclusivity of the defined smallest set is proved, and the implementation of the topological spatial relationship in a spatiotemporal data model is finally discussed.
