Hi all, How would you feel about considering waterway=penstock beside of waterway=canal, waterway=drain to complete pipeline tagging scheme ?
Penstocks pipes are mostly used in hydroelectric power plants to provide high pressure water to turbines. https://upload.wikimedia.org/wikipedia/commons/b/ba/Tossaka_power_station_penstock.jpg I use to tag low pressure water supply infrastructure as waterway=drain or waterway=canal. Example : http://www.openstreetmap.org/way/372743390 and man_made=pipeline + substance=water for the high pressure part (sometimes overground shielded metal pipes going along hills and mountains) Example : http://www.openstreetmap.org/way/372743380 These ways are connected, sometimes with a surge tank depending of the hydraulic circuit configuration. Currently, I find something missing regarding man_made=pipeline + substance=water because a pipe carrying water can correspond to many things in reality. man_made=pipeline + substance=water + *waterway=penstock* would fill the lack. I suggest waterway=penstock because it has the same target as waterway=canal or waterway=drain : a water path more than a pipeline type, part of the global routable water network. waterway=penstock is used 36 times whereas 18 for pipeline:type=penstock (non-reviewed key for pipeline:type out of the scope of the last pipeline extension proposal). http://taginfo.openstreetmap.org/search?q=penstock#values All the best François Lacombe fl dot infosreseaux At gmail dot com www.infos-reseaux.com @InfosReseaux _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
