Original Kurzfassung:
Situation awareness and geographic information systems in
dynamic spatial systems such as road traffic management (RTM) aim
to detect and predict critical situations on the basis of relations between
entities. Such relations are described by qualitative calculi, each
of them focusing on a certain aspect (e. g., topology). Since these calculi
are defined isolated from each other, dependencies between then are not
explicitly modeled. We argue, that a taxonomy - containing a plethora
of special cases of inter-calculi dependencies - can only be defined in a
consistent manner, if evolution of entities and the relations of calculi
are grounded in a unified model. In this paper, we define such a unified
model, which is used to derive a taxonomy of inter-calculi dependency
constraints contained in an ontology utilizing various spatial calculi. The
applicability of this approach is demonstrated with a case study in RTM,
and concluded with lessons learned from a prototypical implementation.
