[Talk-GB] ncn vs rcn

[Richard Fairhurst]

Just a little reminder for cycle route mappers:

If the number is white-on-red, it's a National Route, so you use the  
ncn_ref tag (or an ncn relation).

If it's white-on-blue, it's a Regional Route, so you use rcn_ref/rcn.

If it's a city route (fairly rare), or an unnumbered local route, use  
lcn_ref/lcn.

I've corrected a few 'ncn's and 'lcn's recently to 'rcn's. If you're  
not sure, do look at the National Cycle Network page on the OSM wiki;  
it says where most of the routes go. So if you see (for example) a  
route 41 sticker in North-West Wales, you'll know that it should be  
'rcn' because National Route 41 is in Gloucestershire/Warwickshire.

Bear in mind that sometimes local councils get the signs wrong. ;)
