%X Qualitative reasoning of directional relation is one of the key theoretical issues in GIS. This paper focuses on the qualitative reasoning based on composition operation table of directional relation. First, the qualitative representation of directional relation based on space with neutral zone is introduced. Then, the qualitative reasoning based on composition operation table of directional relation is mainly discussed. Finally, a qualitative reasoning algorithm based on composition operation table of directional relation is also given.
