[Talk-pt] Road numbering in Portugal

[Claudius Henrichs]

I just did some quick Google research. The pictures shown on this page: 
http://www.cbrd.co.uk/international/portugal/
indicate that the road signage for "Estradas nacionais" is always 
starting with just "N" and not "EN". Based on the prevailing rule "tag 
what you can see on the ground" wouldn't it be better to tag them just 
"N329"? Besides it would result in shorter signs on the map ;)

Currently the tagging in Portugal seems to be 50% with "EN" and 50% with 
"N".

And while we are at it:
Do you have a tagging scheme already for the relation which group each 
way that forms a complete auto-estrada/estrada nacionais? Like we do 
have in Germany for Autobahns: 
http://www.openstreetmap.org/browse/relation/21451
In Portugal we would need a network, like "pt:national". The operator 
for most bigger roads would probably be Brisa.

>> ref=EN329 (without space)
>> ref=N 329
>> ref=N329
>> ref=329

>> So to take an example: http://www.openstreetmap.org/browse/way/25410709

>> Currently it's tagged like this:
>>
>> name: Estrada Nacional 108
>> ref: N108

>> ref: EN 108
