Abstract:	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.
