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.

Pro & Contra

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


emergency=fire_hydrant + fire_hydrant:type=suction_point

  • (+) 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


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)
