I don't think we should delete it because "ditch" in reality does stand for both land drainage and irrigation. In other words "ditches" are used to drain surplus water from wetland and supply water to dry land. Whereas "drains" are used to drain storm or waste water or industrial discharge and are usually lined with concrete or similar. I suggest we update the definitions on the wiki to reflect these statement clearly. пт, 11 янв. 2019 г. в 19:01, Markus <[email protected]>: > On Fri, 11 Jan 2019 at 16:42, Eugene Podshivalov <[email protected]> > wrote: > > > > Markus, you can find that in the "How to Map" section of the ditch > proper page: > > "If the ditch is used for irrigation, the usage of irrigation=yes is > proposed." > > https://wiki.openstreetmap.org/wiki/Tag:waterway%3Dditch > > i.e. irrigation ditche should be maps as waterway=ditch + irrigation=yes. > > Oh, please excuse me, I missed that. > > It says 'proposed', so it isn't standard mapping practice.
