Location of built-up areas
containing Extra Large Town centres
Using ArcView the built-up areas containing extra large town centres were
selected and coded with a value, these are displayed as black areas in
the map above.
This layer should help the neural networks distinguish the areas which
have a high population density which also have quite a large distance from
small or medium sized towns, and those areas which have a low population
density and are quite a large distance from small or medium sized towns.
It is also one layer which helps build up a picture of the function of
built-up areas in the EU urban hierarchy.
