Some of you may remember the discussion we had on tagging cardinal directions in the US, which led to the wiki page describing the current practice.
Basically the convention we arrived on is to tag relation members with role=north/east/south/west to indicate cardinal direction.
This is backed up by usage in the US. About 75% of way members of Interstate road relations have directional role members.
The Canadian highway system seems to follow similar conventions, having cardinal directions signposted. (Just picking out one example, )
The Telenav mapping team wants to help map cardinal directions in Canada now, and I have a few questions:
1) Is this way of tagging cardinal directions acceptable to the Canadian community as well?
2) For which regions / highways / highway types is it common to refer to the cardinal direction as part of the name?
2) How to deal with (mostly) single carriageways?
Posting to talk-ca and talk-us cc tagging because I think all three groups may have valuable input.
