Abstract Most of the spatial topological relation models are dealing with the same kind of spatial object,which are restricted in the practical applications at some degree. 4-intersection matrix model is extended to represent the topological relations between a concave region and a simple region with a hole. Thus,totally 161 topological relations are obtained,in which the illustrations of the first 10 relations are given. The algorithm is also presented to prove that the 161 topological relations are all feasible in the real world. The topological relations are proved to be exclusive and complete. Compared with other relative research work,the representation model is more expressive than other similar models.
