A model to represent spatial relations is presented. It is used for the definition of common sense knowledge of rational agents in a multi-agent-scenario. The main idea is, that it is structured in two levels: the representation of relations may be accomplished in terms of predicate logic at one level or in expressions of Cartesian coordinates at the other. Hence reasoning is possible with common rules of deduction as well as via exact calculations of the positions. Here we give an overview on the whole structure and then investigate in the the definition of a set of spatial relations at the "Logical Level". Finally special features like the handling of the context and the problem of multiple views are discussed.
