Hi, everyone.
I often get confused about other people’s use of tags.

  1. I think that the ‘guard post’ tag should be activated anew for a guard post that is not a prosperous building.

  2. Until a new tag is agreed upon, I think the ‘amenity=security’ tag is appropriate for watchtowers and guard posts.

  3. I think this should focus on the role, not the building.

  4. I think ‘surveillance’ should only be used for features for surveillance purposes.

  5. However, this feature also serves several other functions, such as verifying ID or guiding.

  6. Some people recommend ‘gatehouse’, but I think that gatehouse is only applicable to buildings that serve as both a gate and other roles.
    I don’t think it’s applicable when it’s a simple building that doesn’t play any other roles.
    (gatehouse = gate + buildings with different roles. A building that does not play other roles is not a ‘gatehouse’.)
    Tag:building=gatehouse
