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.
