Re: [Tagging] Underground power lines in tunnel

If you look at my entire message, I did point out that vertical clearance was an attribute of the ways, not the bridge. How should the vertical clearance from the bridge to the water be tagged, and how do you tag what height of water was the reference point? If the water level is high, there

There are three height types for a bridge over a navigable waterway: the maximum distance from ground level to the highest part of the bridge structure, the maximum height of vehicle plus cargo that can go across the bridge, and the maximum clearance for vehicles passing under the bridge. The

Hi, I agree with you Martin. And that's why I'm looking for a way to say those power lines/lanes/roads are on the same bridge/tunnel. As you mentionned, the tunnel/bridge name can precise which bridge is but it's not a relational (or even spatial) way of bringing objets together. Ok a tunnel

2013/6/5 Martin Koppenhöfer dieterdre...@gmail.com: yes, but you can easily see whether it is one tube with both directions going through, or if there is one tube per direction (more usual case due to security reasons). Then you still have to define what is one tunnel, maybe also 2 (or more)

One reason it would be useful to be able to tag bridges (and, to a lesser extent, tunnels) as single physical objects is that they may be used as landmarks. For example, you may be traveling along a street that runs parallel to a river, looking for a location just past a certain bridge. If

Thanks fly for this answer. Type=tunnel can suits my needs : let's add all power lines in the relation with role=through. Add tubes or not depends on the tunnel design, not on what's inside. I don't mind. The trick is to link many power lines to a single tunnel. However, it would be hard to

Hi That's already a problem for ways, too: A motorway with two separate highways in OSM may be one bridge alltogether - but is mapped as two. A street where the footways along are separated by a small wall or a hedge is drawn as distinct osm ways (at least it should be) but if these ways share the
