At present, there isn't a clear definition and description of spatio temporal topological relationships which is a conceptual and formal basis of spatio temporal data model. In this paper, after analysis of the spatial and temporal properties of GIS, a semantic definition of spatio temporal topological relationships has been suggested. Moreover, we have presented and proved a 4I framework used to describe temporal topological relationships completely and uniquely, listed a set of predicates describing temporal topological relationships, distinguished the intention and the predicate description form of temporal topological relationships and time direction relationships.
