[Talk-pt] Road numbering in Portugal

[Claudius Henrichs]

Bom dia!

sorry for posting in English, but I feel this to be a relevant 
information and question.
Some of you actively mapping in Portugal may have seen altely some 
increased activity from some german mappers. This is because a user who 
is active in quality assurance has run a "connection check" over the 
portugese OSM data. This check searches for roads that are crossing 
without bridge or tunnel. There is a list with those errors on the wiki 
[1] and every user can take a block of 100 errors, leave a note in the 
wiki that he is dealing with them and try to fix these. Fixing the 
errors is much easier now with the help of Bing imagery.

I feel that it would have definitely been nicer to have informed the 
portugese OSM community *before* starting this campaign, but better late 
than never.

Now to my personal question on mapping in Portugal: I have read a bit 
about the road network and number in Portugal on the english wikipedia 
[2]. I see that you have some new road numbers starting with "IP" and 
"IC" that were assigned in the 2000 Plano Rodoviário Nacional. And then 
you have the older estradas nacionais given out in the 1945 Plano 
Rodoviário Nacional. I already checked the OSM wiki project page for 
Portugal [3] but could not find any recommendation about how to tag 
these. Shall I use "EN329" or "N329"? Same goes for the estradas 
regionais: Should we use "ER32" or "R32"? Thanks in advance for your help.

Regards,
Claudius
