Hi, according to waterway=*, pressurised is not more specific than canal, it's just another way to carry water.
Then, it sounds not correct to only set waterway=canal since irrigation water can also be brought by pressurised pipes or tunnels. Usage doesn't assume anything on how things are built.
This has been discussed and reviewed on Proposed_features/Hydropower_water_supplies and need discussion prior to change wiki please Fanfouer (talk) 15:26, 15 July 2018 (UTC)
- @Fanfouer I know this proposal. It's yours.--Norcross (talk) 15:34, 15 July 2018 (UTC)
- I don't get your point. Mine is to not change or move focus on what has been discussed without brining any new benefit.
- Wiki is made for everyone looking for documentation. Removing combination (which feeds taginfo and more tools not to mention) will break things and may confuse undergoing key adoption. I confirm that usage=irrigation can be combined with both waterway=canal and waterway=pressurised. Fanfouer (talk) 15:45, 15 July 2018 (UTC)
