[Tagging] Feature Proposal - RFC - Fumarole

I’ve added a section to the wiki page. In short: don’t map inactive ones, unless they’re very significant, then a lifecycle prefix could be used if a mapper really wants to map them.

I’ve updated the page to allow Areas

what do you mean by inactive fumarole? If a fumarole is a place where steam and gases emit through the crust of the earth, are all other places where the crust in not permeable inactive fumaroles?
Places which are clearly recognizable/signed as a place where steam/gas was emitted
but is not anymore.

If I understand it right, then https://commons.wikimedia.org/wiki/File:FunnelFumarole.png
is example of such object
By the currently proposed definition, there is no risk of inactive fumaroles getting the tag.
natural=tree used to be clearly defined as "Lone or significant tree"
https://wiki.openstreetmap.org/w/index.php?title=Tag:natural%3Dtree&oldid=14739

(no idea is it likely that natural=fumarole would end in the same way)


2) is restricting to nodes a good idea? How cases like

https://commons.wikimedia.org/wiki/File:Fourpeaked-fumaroles-cyrus-read1.JPG
https://commons.wikimedia.org/wiki/File:Kamakura-021_hg.jpg
would be tagged?

right, from reading the WP article I also got the impression that this phenomenon can occur along longer cracks, so ways seem suitable in some cases, as might areas.
I also thought about tagging fumarole groups/fields as an area.

Especially as such structures may be dangerous to survey.
