  • This paper used the description frame of two regions with holes which was put forward by egenhofer,based on the 4ID,put forward a new extended model 4-4ID,which can describe the regions with a hole's special topological relations.At the same time,this paper presented the topological relations between simple regions and regions with a hole.
