Hi!<br><br>I wanted to add in «Obstacle» page, the keys obstacle=bridge and obstacle=lock that are in use, but not documented. There are values that refers to obstacles in waterways.<br><br>I have a doubt... I think that obstacle=bridge is a value consistent with the obstacle definition: <a href="http://wiki.openstreetmap.org/wiki/Proposed_features/Obstacle#Differences_with_other_keys">http://wiki.openstreetmap.org/wiki/Proposed_features/Obstacle#Differences_with_other_keys</a><br>
But I'm not really sure with the key obstacle=lock , because I think that could be better use barrier=lock or man_made=lock (I'm not a marine, and I don't have a exact idea about what is exactly a lock or a lock gate). The question is that this key=value is used more than 400 nodes and ways (<a href="http://taginfo.openstreetmap.org/keys/obstacle#values">http://taginfo.openstreetmap.org/keys/obstacle#values</a>), I must add this value on the page? (Although I don't think is really an obstacle?)<br>
<br>Another question: Someone knows what refers the key obstacle=line?<br><br>Thanks!<br><br>ALBERT<br><br><br><div class="gmail_quote">2012/10/29 Martin Koppenhoefer <span dir="ltr"><<a href="mailto:dieterdreist@gmail.com" target="_blank">dieterdreist@gmail.com</a>></span><br>

<br>
</div>it is clear: it will be tagged on the way it refers to. If two ways<br>
have a node in common, you shouldn't tag the obstacle applying only to<br>
one way on this crossing node but be more precise. If you tagged the<br>
node in common it would apply to both ways.<br>
<div class="im"><br>

<br>
<br>
</div>+1, that's how it would be done. Basically there is no particular<br>
problem with this tag here, it is just the same as other barrier-tags<br>
or maxheight for instance.<br>
