Tagging Firefighter Training Towers: building=tower vs man_made=tower?

Hi everyone,

I’m looking to clean up my tagging for fire station training towers. Traditionally, I have been using:

building=yes
man_made=tower
tower:type=firefighter_training

but I see now its possible to simply go:

building=tower
tower:type=firefighter_training

My questions:
Is this correct? Can I simply do the later and drop the man_made or do some renderers still need the man_made? i.e.: keep both?

can you post photo(s) of these towers?

likely some are buildings and some are not, maybe all of yours fall into one category

As far as I read and understand the wiki there is no (real) difference between man_made=tower and building=tower. As mentioned by @Mateusz_Konieczny there are different types of constructions possible so I would tag them differently. As a rule of thumb:

  • For towers primarily made from steel frames or similar (constructed very “open”) I would use man_made without building=yes. Example: Mapillary
  • For towers with solid walls and a roof I would tag building. Example: Mapillary
    Another point: If the tower is attached to the other buildings of a fire station there are probably also used for hanging the hoses - this would indicate building or even building:part for me

I would try and may these things like “most other people do”. There are 324 tower:type=firefighter_training, and of those only one** has the combination nwr["tower:type"="firefighter_training"]["building"][!"man_made"];.

** it was two but I just retagged one in Horwich.

This is an excellent answer. Thank you @BjörnSc.

btw: its possible to add a tower:construction=freestanding
