The basis of visualisation and interaction processes is a thorough analysis and formal description of the fact sets involved and the action contexts of the system components under consideration.

The amount of spatially bases management information systems used for real-time information management and decision making is rapidly increasing. Thus, the descibing elements of «Situation» and «Strategy» have to be defined and examplified along with target definitions that may be dynamically varying (considering sytem variation during the decision process).

This contribution shows, which structural elements of semiotics can be used to describe the complexity of action-oriented information systems. For cartographic purposes it can be shown that this would lead to a traceable analysis of the visualisation process and simultaneously leads to reviewable valuation of the fact sets used.

Decision-oriented cooperative processes will become transparent and controllable by applying these methods.

The concept shown in this paper clarifies the adaptability of formal methods from cognitive science for the software engineering of active spatially based information sytems.
