Hi.
I agree that the schemes could possibly coexist.
What I'm missing currently at the option to tag sidewalks as tags at the
main street (the option [1]) is the possibility to tag detailled crossings.
How to tag attributes of a e.g. zebra crossing differing between left
and right of the way?
Including "namespaces" left and right might be okay at ways, but the
crossing itself is usually tagged on a node of the way, if the sidewalks
are not mapped separately.
The "hack" around that would be to map sidewalks separately around the
crossings itself - but then there is no argument left to not do that
everywhere in the city, too.
If anybody has a solution to tag crossings with tags only at the
street's way, I would appreciate to learn more.
My target group are especially people with impairments - blind people or
people with wheelchairs. Here curb heights (sloped_curb), tactile
pavings (tactile_paving) and features of traffic signals are especially
important.
regards
Peter

Serge,
I think we're really talking about two proposals here, both of which
have merit. The linked proposal has been around for a while, and
involves tagging the road to indicate the presence of a sidewalk walk
on one or both sides of the road. David refers to this proposal as
"deprecated" [1].
What David proposed, and what I'm interested in, is mapping the
sidewalk as a separate way from the road. This rough proposal is on
his page here [2].
I think both schemes can coexist. In cities, especially ones with
regular grids, the first scheme might be preferable for simplicity.
However David's scheme has advantages when sidewalks don't have a
constant offset from the road, and if there is a desire for precise
navigation. In my area of suburbia, I plan to use David's scheme.
We should certainly link both together though, so users can determine
what level of detail is appropriate.

As per the discussion last week about Sidewalks, I'm re-opening the
sidewalk proposal as per:
http://wiki.openstreetmap.org/wiki/Proposed_features/Sidewalk
We've already had some preliminary discussion on this tag and there's
been very minimal disagreement, which is a good sign for its adoption.
NAK.
What I understood was that the first tagging example of my page was that [1]
was generally accepted.
Erm.. ok, I hope it was understandable :)
I don't understand, so maybe you can elaborate.
David, you expressed some interest in this last week, and Josh
suggested that since you were so interested, you make the proposal,
but I didn't see anything, and I have a specific project I want to use
these tags, so I've gone ahead and done so.
If you have specific issues with the proposal, please bring them up
for discussion.
