Mapping two different features with one OSM object shouldn't be done, especially for a pipeline vs a street Both don't have the same location (one underground, one IS the ground). Both don't have the same shape (such a pipeline can cross the street many times, how would you represent this ?). ... they don't share many properties. Editing software should adapt to such issues, not the DB. Then : man_made=pipeline name=West 4 flow_direction=both usage=transmission location=underground Cheers *François Lacombe* fl dot infosreseaux At gmail dot com www.infos-reseaux.com @InfosReseaux <http://www.twitter.com/InfosReseaux>
