Title: Streets to the OPRA - Finding your destination with imprecise knowledge

Abstract: Qualitative spatial calculi offer a method to describe spatial configurations in a framework based on a finite set of relations that abstracts from the underlying mathematical theory. But an open issue is whether they can be employed in applications. Further their cognitive adequacy is questionable or not investigated at all. In this paper we investigate the applicability of OPRA to navigation in street networks that are described via local observations. Further we scrutinize whether a description of directions that is deemed cognitively adequate and can be described in OPRA can perform that task. We are using an environment that we developed ourselves for these experiments, the used algorithms and the program itself are explained in detail.
