Converse interface map is the converse of the interface map, in which each building or boundary is still represented by a dot and each convex space by a circle, but each line is drawn only where there is a relation of adjacency and impermeability. Thus, the lines linking buildings and boundaries to convex spaces will represent blank walls.
