Re: [Talk-ca] Green alleys in Montréal (ruelles vertes)
Hello Richard, Thanks for your reply! You can see alleys as a destination-only road: you can drive through them, but they are definitively not a shortcut, as you need to drive slowly. It seems that a living street is still a street, i.e. you have the main entrance of houses on the living streets. Green alleys (and alleys in general), at least in Montreal, are service roads between two roads. For example, take this alley in Montréal: http://www.openstreetmap.org/browse/way/218960041 It is a small, one lane road between the Wolfe and Amherst streets. It separates the buildings of both streets and provide access to local residents' backyard or parking. I have created a wiki page for a new alley=green_alley tag: http://wiki.openstreetmap.org/wiki/Proposed_features/green_alley I also posted on tagging: http://lists.openstreetmap.org/pipermail/tagging/2013-August/014514.html Guillaume Le 2013-08-17 à 23:29, Richard Weait rich...@weait.com a écrit : On Thu, Aug 15, 2013 at 9:53 PM, Guillaume Pratte guilla...@guillaumepratte.net wrote: Hello, I would like to have some advise on how best identify green alleys in OpenStreetMap data.

Green Alleys look pretty great. I was not aware of them before this thread. If I understand the article that you linked, it appears that there are some widely varied Green Alleys. For example, some allow vehicles and some don't. From the point of view of OpenStreetMap data, that's fairly important. It may be that a single green Alley tag, just won't be sufficient. Fair enough. Other tags are lacking in that way as well. A quick look at taginfo found several places named Green Alley, but no keys or non-name tags for green alley. So it seems the term is not presently in use in the OpenStreetMap database. I suggest two things. For tagging now, and adding Green Alleys to the data base as the opportunity arises, use un-controversial tags. highway=service; service=alley, seem pretty clear. Access tags like vehicle=no; foot=no; bicycle=no seem like they would be useful when they depart from typical values for highway=service. For any new tagging, I think you'll want to consult more widely than just talk-ca. I wonder, in this case, if a Green Alley is close enough to a living street to share a tag? talk@ or tagging@ seem like a good place for the discussion.

Re: [Talk-ca] Green alleys in Montréal (ruelles vertes)
Hi Guillaume, my two cents: since this seems to be a feature that is pretty much unique in Montreal, you'll probably have to come up with your own tagging. I would not introduce a new tag on the service=* level, as these primarily still appear to be alleys and a new tag on that level might break existing applications. So I'd say you could come up with something like: highway=service service=alley alley=green_alley plus whatever other characteristics the alley has (surface=*, smoothness*, access=*, ...).
