[Tagging] Penstock vs aqueduct
Hi, I'm currently wondering how can I map make the difference between pentocks and simpler water aqueducts. A penstock is used in hydro power plant to feed turbines with pressurized water, it's shielded and sometimes in tunnels to ease works around it. Instead of a an aqueduct which is not only used in hydro power plants and generaly builded to bring water from source to consumption. Hydro power plants may use both since water can be catch from different valleys and concentrated through aqueducts to a shaft where we can find penstocks above turbines. Aqueducts are often totally flooded with water and no one could get inside when it's in operation. It would be great to make that difference on maps. Penstocks are pipes, so I'm tempted to use man_made=pipeline + type=water but what best describe an aqueduct ? A proposal can be found on wiki but it's only for historical aqueducts. http://wiki.openstreetmap.org/wiki/Aqueduct The link between pentsocks and aqueducts is called a surge tank and it absorbes large amount of water when operator opens/closes valves. I remember we had talk about it on that list last April. And think about NY City Water tunnel #3 which is currently in construction. For me it's more an aquduct than a penstock. http://en.wikipedia.org/wiki/New_York_City_Water_Tunnel_No._3 Cheers. *François Lacombe* francois dot lacombe At telecom-bretagne dot eu http://www.infos-reseaux.com ___ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
Re: [Tagging] When was landuse=reservoir deprecated ?
How do we go from here? Can someone write a summary? Could someone please state the results in the wiki? Thank you. Wie geht es nun weiter? Kann jemand eine Zusammenfassung schreiben? Könnte bitte jemand die Ergebnisse im Wiki dokumentieren? Vielen Dank. Gruß René ___ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging

I have already un-deprecated the tag on the wiki two weeks ago. I had shortly after set the tag status from abandoned to approved, but someone told me it should better be de-facto (if this is a common status I'd agree, indeed I thought the tag was approved by active use regardless of votings) and I was told that the deprecation was (besides other stuff) decided here: Proposed features/Water detailshttp://wiki.openstreetmap.org/wiki/Proposed_features/Water_details and that *natural=water + water=reservoir *should be use instead (btw.: don't agree, landuse and physical characteristics are orthogonal properties). cheers, Martin ___ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
