A tunnel doesn't sound like a proper pipeline to me Especially because a pipeline can be hosted in a tunnel. https://wiki.openstreetmap.org/wiki/File:Waterway_pipeline_in_tunnel.png <http://www.twitter.com/InfosReseaux> 2018-02-14 0:51 GMT+01:00 Warin <61sundow...@gmail.com>: > OSM unfortunately 'maps what is there' .. not "hardware"/"use". > Then it isn't clear to me why we use to tag an underground road with highway=primary + tunnel=yes We actually do have well established tagging which separate content from containers. I don't get the point about waterway=pressurised. Is this that bad, or you just don't want ot use it? François
