[OSM-talk] waterway=lock

[Mike Harris]

I have tried various systems for this one. At present I favour tagging two
nodes - one for each gate (or multiples of 2 for complex locks e.g. Vale
Royal where there are two parallel locks, each with - of course - two
gates), isolating the section of canal between and giving this the tags
name= and ref= . I have no strong opinion - beyond wishing to record the
name and number of the lock - and would be interested in other views. Not
keen on using name_1 - prefer the ref= tag.

Not quite clear whether you add identical name= and ref= to each of the two
gates?

On a related canal issue, I have a problem with deciding how to tag a canal
bridge as a segment of a way. The way will often already have name= and ref=
tags as a highway; but I want to add a name= and ref= tag for the canal
bridge. Not keen on name_1 or ref_1 - any better ideas? I did wonder about
adding a node in the middle of the bridge and then tagging this with the
canal bridge information and reserving the name and ref tags for the highway
segment.
