You can get the coordinates using DoFTools::map_dofs_to_support_points(). As for the direction: That's something that the RT element does internally using a convention that takes into account the two adjacent cells. I don't think there is a way to determine this direction outside the element short of evaluating the shape function at a point on the face.
