| Abstract: | In order to represent the equivalence of topological relations between a line and a region in vector space,on the basis of 97 topological relations between a line and a region,which are depicted by combinatorial reasoning of spatial topological relations,the questions of equivalent transformation of the basic topological relations types in abstraction process are discussed.The equivalent transformation methods of component abstraction are presented,then applied in the abstraction of basic topological relations types between a line and a region,and the corresponding equivalent transformation maps have been drawn. |

| Keywords: | spatial topological relation equivalent transformation combinatorial reasoning spatial data generalization |
