standpipe is ambiguous. it is used in the US for both wet and dry risers, and in the UK for wet & dry risers (a secondary term riser being primary in the UK) as well as for the pipe used to provide connectivity to underground hydrants. so i think it should not be used at all, since you wouldn't map the standpipes in the UK (they're mobile after all.) so riser for the in building systems is consistent with UK usage and the way we should go. however, it turns out that riser terminology does not use the term hydrant (it uses the terms outlet and inlet in the obvious way), so i will drop it from the water source specification. finally, i have found references to pillar as a hydrant type. i was not insisting on it going away, merely questioning where it came from, so now i'm ok with leaving them as is. however, there are more specific types available, so i will propose adding dry_barrel and wet_barrel to the allowable fire_hydrant:type tags. it's fairly easy to distinguish between the two types; dry barrel hydrants are the norm in climates where the ground freezes, and wet barrel hydrants are the norm in warm climates. the nut that operates the main valve of the dry barrel is a dead giveaway for the hydrant type, so it's easily detectable by mappers. how does everyone feel about these changes? richard -- [email protected] Averill Park Networking - GIS & IT Consulting OpenStreetMap - PostgreSQL - Linux Java - Web Applications - Search
