[Tagging] waterway=penstock to complete pipeline tagging

[François Lacombe]

Hi Colin,

Ok let's follow the analogy between a pipeline and a route.
In OSM, it is surely a relation linking several ways together.

Two questions :
Do you mean that any covered man made water diverting and transport
facility would correspond to a pipeline ?

I don't know how to use the OSM accordingly : man_made=pipeline hasn't
been designed to fit on relations.
How will we deal with "route" pipelines and pipeline ways separately ?

Furthermore, what is the difference which we should consider between
drains (waterway) and pipeline (man_made) ?


All the best
François Lacombe
