Abstract: In this paper we introduce a visual language for the specification of temporally changing spatial situations. This extends existing concepts for visual spatial query languages, which are only capable of querying static spatial situations. We motivate the language design and describe the translation into a formal model of spatio-temporal predicates. The visual notation can be used directly as a visual query interface to spatio-temporal databases, or it can provide predicate specifications that can be integrated into textual query languages leading to heterogeneous languages.
