Abstract
In this paper, we have presented a formalism for representation of and reasoning about directions in a qualitative way in an egocentric spatial reference frame. Qualitative direction has been separated from dimensionality of spatial objects and as such, the formalism may be used to represent qualitative direction in a dimension-independent way. The formalism uses fewer number of base relations than existing formalisms and granularity can be refined easily. Algorithms for finding composition and converse of base relations have been presented.
