The proposal https://wiki.openstreetmap.org/wiki/Proposed_features/Hydropower_water_supplies introduced the tags waterway=pressurized for non-pipeline waterways that are completely filled with water.
It also introduced tunnel=flooded for waterways and pipelines, and the wiki page has this description: https://wiki.openstreetmap.org/wiki/Tag:tunnel%3Dflooded "A flooded tunnel is an artificial structure intended to channel water on a significant distance. Its dimensions and length allow human to fit inside but safe walking is impossible due to high amount of water or other fluid expected in operation. Such tunnels are different from tunnel=culvert where human usually can't enter and for which dimensions are restricted to building or way it is supposed to go underpass. They are also different from man_made=pipeline since a pipeline is built from tubes assemblies." I'm a little confused about how to decide when to use tunnel=flooded vs tunnel=yes with waterway=canal or other free-surface-flow waterways. Is this tag meant to replace all instances of tunnel=yes for large waterways, or are there situations when tunnel=yes with waterway=canal would still be needed? -Joseph Eisenberg _______________________________________________ Tagging mailing list [email protected] https://lists.openstreetmap.org/listinfo/tagging
