[OSM-talk] difference between waterway=canal and waterway=drain

[Raphael Studer]

Hi,

As a not native english speaker, I'm looking for the difference between
canal (http://wiki.openstreetmap.org/index.php/Tag:waterway%3Dcanal)
and
drain (http://wiki.openstreetmap.org/index.php/Tag:waterway%3Ddrain).

By looking at the Map Features, there are nearly the same.

Canal: An artificial open waterway used for transportation,
waterpower, or irrigation
Drain: An artificial waterway for carrying storm water or industrial discharge.


Thanks for your help.
