Research on qualitative spatial reasoning has produced a variety of calculi for reasoning about orientation or direction relations between point objects or line segments. Altough it is obvious that some calculi are more general than others, the exact relationships between the calculi have not been investigated thoroughly. We show that many well-known orientation calculi can be expressed in the more general OPRAm calculus which allows to translate information from one calculus into another. In addition, we demonstrate that the mapping can be exploited to automate typically complex tasks like determining or verifying composition tables.
