Talk:Tag:emergency=suction point

From OpenStreetMap Wiki
Jump to: navigation, search

Hello, my name is Robert and I'm the author of OsmHydrant, an easy-to-use OSM-editor for fire water facilities (i.e. fire hydrants, water tanks and suction points). I wanted to grab some opinions upon emergency=suction_point vs emergency=fire_hydrant + fire_hydrant:type=suction_point.

As I'm writing this, there are 1020 nodes of fire_hydrant:type=suction_point, mostly used by the Polish community.

In contrast, there are 1165 nodes of emergency=suction_point, mostly used in Germany as well as by my fire-water-facility editor OsmHydrant

I think the OSM community should find consensus upon which tag to use.


A suction point is a preferred place to get fire water like shown in this picture: suction point

At such places there are no prepared connectors where you just connect like on a fire hydrant, but they are prepared or suitable locations to place fire pumps. Suction points may be prepared at rivers, ponds and underground water-tanks.

Related stuff

When searching for fire water facilities (besides suction points) there are not only fire hydrants, but also water tanks and fire water ponds.

But a fire hydrant can be connected to a water system, a tank or a pond. It's simply not the same thing and the emergency=fire_hydrant objects should be qualified with their source. Fanfouer (talk) 15:50, 12 August 2017 (UTC)

Pro & Contra

(+) means in favor of, (-) states a contra for this tagging concept.


emergency=fire_hydrant + fire_hydrant:type=suction_point

Then it's not a fire hydrant and emergency=suction_point should be used Fanfouer (talk) 15:55, 12 August 2017 (UTC)
  • (+) you only need to query for emergency=fire_hydrant when you're searching for fire water (besides water tanks, but they might not be always usable) and somehow they belong together
+1 for query but the sentence should be you only need to query for emergency=fire_hydrant when you're looking for connectible water sources. A water tank, pond or suction points may not be built with hose or connectors.
Anybody looking for suction_point will have to bring the appropriate material (like pumps, pipes or whatever) to deal with it Fanfouer (talk) 15:55, 12 August 2017 (UTC)


We should find consensus to avoid going two directions for the same thing. Having one way of tagging suction-points would also ease future work.


You should start a discussion at the regarding Mailing lists/Forums to reach some mappers. IMHO this place is least likely to be found. After a consensus more or less is reached you should announce a mechanical edit before you change one of the tags. Sorry that it sounds a little complicated and tedious, but that's the way it is supposed to go. -- malenki 19:37, 22 February 2015 (UTC)
