watmildonA user in the OSM discord posted this screen grab from their flight sim. A bit of overpass querying and sleuthing leads you to this delightfully typo'd building:levels tag.
A classic.

Deborah Pickett@watmildon Haha there was one of those a few years ago in Melbourne. I was the one who found the typo in OSM. https://www.engadget.com/flight-simulator-open-street-map-building-205545509.html
@futzle YES! I was instantly thinking about this one!! Thanks for tracking it down and being part of a great chuckle I had years ago.
There’s also a building import in Japan that I stumbled on that has some that are 9999. They are aware now and working on it. https://github.com/yuuhayashi/citygml-osm/issues/128
注意： height=-9999 など、PLATEAUのNull値やダミー値が含まれている CityGML が存在する · Issue #128 · yuuhayashi/citygml-osm
2024年の PLATEAUデータの一部に height=-9999 など、PLATEAUのNull値やダミー値が含まれている CityGML が存在するので、.gml から .osm を生成したときのJOSM妥当性検査後、該当するタグは削除したほうがよさそうです。 CityGML .gml ファイル 内の記述例 <bldg:measuredHeight uom="m">-9999</bld...
SomeoneElse@watmildon @futzle Doesn't anyone sanity check inputs any more?
When I added "tree size rendering code" to a map style I excluded the many unparseable or implausible ones.
I feel very old...

@SomeoneElse @futzle If the OSM api can't be bothered to sanity check anything I'm not sure we can blame our consumers.
But, if I am being completely honest, I love an incidental QA layer and would be sad if we never had another flight sim super tower incident.
@SomeoneElse @futzle Out of curiosity, it turns out Overture also contains this error. Apparently no one does any sanity checking, even the folks who want to sell a sanity checked data set.
@watmildon @futzle It'd be a bit of a stretch for the OSM API to enforce building:levels limits - https://www.openstreetmap.org/way/241029253 is nearly at that size, https://www.openstreetmap.org/way/446646206 is way over.
Perhaps a QAed general dataset from Overture ought to contain sanitised values in that field, but I'd suggest it's more of a key requirement for someone feeding that data into a _flight simulator_ !

Neville Park@watmildon how the HELL did urban planning sign off on that
