Abstract of FKI-230-99

In the discussion of spatial representations in technical as well as in biological systems, frames of reference are of great importance. In this paper, we focus on spatial frames of reference in motion representation and stress that we have to introduce a distinction between frames of reference in measurement and in representation. We discuss some problems that arise in qualitative motion representation when measuring the course of motion in the egocentric and the allocentric frame of reference. Then we present a method to automatically generate route descriptions from these qualitative representations where granularities and frames of references can be mixed.
