Representing Topological Relationships for Moving Objects

Several representations have been created to store topological information in normal spatial databases. However, not that much work has been done to store such relationships for spatiotemporal data. This paper extends the representation of moving objects from [7] so that it can also store and enforce some of the topological relationships between the objects. This is done in a fashion similar to the Node-Arc-Area model for normal spatial databases. One use of such a rep resentation is storing a changing spatial partition.
