Generally, where a lock has been built, this is in an artificial cut slightly away from the main flow of the river. This is usually referred to as the "lock cut". In some places this is not that much longer than the lock itself (often the case on the Thames), whereas in others it can be significantly longer (the Aire & Calder/Calder & Hebble). Meanwhile, the main course continues over the weir. As "cut" is usually a synonym for "canal" and they're artificially constructed, it's fairly justifiable to describe a lock cut as waterway=canal, I think. I guess you could put the whole lot in a river navigation relation if that... floats your boat? cheers Richard -- Sent from: http://gis.19327.n8.nabble.com/Tagging-f5258744.html _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
