Ireland South relief map A4 at 1/1 400 000 - Dorrigo

Rather than printed on paper, relief maps are printed on flat plastic sheets then vacuum formed over a scaled model of the area. Vertical dimensions are often exaggerated slightly to enhance the map. However, it isn't as simple as that - as we need to make sure the printing on the map isn't distorted after the vacuum forming is complete so the map features end up in the right place. Great skill and attention to detail is required to ensure perfection. Enjoy!
