As you are well aware, there is no rigorous definition of axial lines, so

Hi - I'm confused,
Rui, could you say ( in simple terms an architect like me could follow) in what way axial lines are undefined in a way that GIS road center lines are ?

p.s If road centerlines are equally undefined then just don't reply to this mail.
