....characterize how a topological relationship between two spatial objects unfolds in a temporal sequence. This notion, referred to by Erwig and Schneider as developments [3] has inspired the approach contributed in this paper. Erwig and Schneider have also devised a two dimensional visual language [4] for specifying these temporally changing topological relationships, and translating them into a sequence of spatiotemporal predicates. However, their approach seems to focus on the representation of topological relationships, whereas the approach described in this paper can be used to capture a ....

....starting with a small set of elementary ones. We have demonstrated how these concepts can be realized in a relational model and how SQL can be appropriately extended to a spatio temporal query language called STQL to enable the querying of developments. The second application described in [21, 22] deals with the user s problem of comfortably specifying temporally changing topological situations and predicates. For this purpose, we have proposed a visual language which extends existing concepts for visual spatial query languages, that are only capable of querying static topological ....
....new predicates according to his needs. To support the user, we have contributed to a solution of these problems (see also Section 2. 2) by proposing an extension of the well known query language SQL to a spatio temporal query language called STQL [19] and by providing a visual query language [21, 22]. STQL enables us to textually formulate spatio temporal queries that relate to developments of spatial objects over time and that are hence based on spatio temporal predicates. Moreover, a macro definition mechanism allows the user to compose more complex spatio temporal predicates from more ....
