    Graphical Abstract
    • Abstract
  • Graphic simplification can cause the transformation of local topological relations between lines,line and region,regions and that after combinatorial.On the basis of abstraction of local topological relations,the rule of local topological relation between lines is emphasized,and the disciplinarian of combining the adjacent local topological relations is investigated.The method of deleting local topological relations is proposed.
