Abstract: A framework for the representation of qualitative
distances is developed inspired by previous work on
qualitative orientation. It is based on the concept
of ``distance systems'' consisting of a list of
distance relations and a set of structure relations
that describe how the distance relations in turn
relate to each other. The framework is characterized
by making the role of the ``frame of reference''
explicit in the context of distances. The composition
of distance relations as main inference mechanism to
reason about distances within a given frame of
reference is explained, in particular under
``homogeneous structural restrictions''. Finally, we
introduce articulation rules as a way to mediate
between different frames of reference.
Keywords: distance systems, frames of reference, representation
of spatial knowledge, qualitative
