Shall we paint the outhouse red, green or blue ??
It doesn't matter if the busstop is on the right or left side of the
road... Neither OSM wise, nor in the real world. In the real world you
use your eyes and see the busstop. With regards to OSM, you apply a tag
to the node indicating position of the busstop, relative to the road.
I.E : k="placement" v="left|right|middle"
It doesn't even need to be rendered on the left or right of the road on
the map, but it could be.
We are not trying to make a virtual copy of the world with the rendered
maps, we are trying to make a fairly accurate visual representation of
the world with the maps, that can be used to orientate and possibly even
navigate around in the real world.
Compromises are made everyday on the renderings of both our and any
other maps. Thats one of the parts of cartography - Deciding what
compromises to use in order to make a map for a specific purpose.
So just tag it with common sense, instead of having 2 months of
discussion on the mailing list - Next people will want to set down
subcommittees that need to deliver reports on best practices for mapping
the wastebaskets and their type at the busstops, which then has to go
through a hearing in the OSMF, and put to a consensus vote twice in a
year, before being vetoed by some goat-hearder mapping trails in outer
mongolia, since he doesn't think a wastebasket position should be mapped
at all, if goat-dung positions isn't mapped as well...
We could call it "Working the EU-OSM way..."
