OpenStreetMap
Objects in private gardens which do not require a build permission, such as small shelters and especially movable objects like (round) swimming pools, should NOT be entered into ANY public maps! They add nothing to the quality and usefulness of a map, I consider it a map data spam.
I may sometimes remove such objects from the Frýdlant region, especially if not mapped correctly (private swimming pools must be marked as private to not interfere with searching for nearby swimming pools).

I support this sentiment. If I map a private pool at all, I always check if it’s one of those fixed pools that are built in the ground. Movable private pools are out of scope for OSM.

Movable object should not be mapped, right. But you shouldn’t delete fixed pools just because they have missing tag. You can add access=private instead.

I’m in favour of mapping permanent/fixed pools (with access=private). It’s a useful way of gauging the affluence of an area. Also, in some places I think public health authorities have used OpenStreetMap data to identify private swimming pools to inspect for mosquito breeding.

Let me explain the background why I wrote my post. There’s been a highly active mapper who apparently added small private swimming pools just for fun to the area which I take care of. It’s been just chaotic, where he mapped like 5% but left out the most. None of them were marked with access=private. And now a few years later it’s clear that it is utter nonsense to map such pools, a high number of those pools is gone (according to aerial maps), which doesn’t surprise me. It’s just more work for me as a mapper to fix it. It’s simply nonsense. BTW mosquitos cannot breed there because of chlorine.

And yes, I fixed some of them with access=private, but I am strongly against adding more of those round small pools in private gardens, it doesn’t make any sense. We don’t add garden furniture either :-D
