I do not speak Polish so I used Google Translate.

An object with layer=1 can of course touch the ground. It is just used to describe the vertical relation of objects, nothing else. Bridges with layer=1 also often touch the ground and don't hover. Do all the pillars of a bridge have the same foundation? I guess not. Are the pillars of a bridge not part of the bridge?

The different properties can be mapped using building:part.

You are saying that there are terminals and jet bridges. Well, the jet bridges are not mapped at all a this airport so what is mapped now must be part of the terminal then.

There are enough images that show how the building looks from the outside. The number of floors inside has no affect on the outer properties. This airport building is not much different from other airport buildings after all.

Bzw. das stimmt nicht ganz, ich habe auch die neue Bahn nicht selber eingezeichnet, sondern nur erweitert.

Bei der neuen Linie habe ich mich nur an der alten orientiert. Auf mich geht das also nicht zurück. Ich habe jetzt keine Tiefgründige Recherche betrieben, aber das könnte der Ursprung sein: osm.org/changeset/2578178

@Yog Sot
Why not? One could use tunnel=building_passage but not tunnel=yes. It is not a tunnel.

I have started a discussion on this issue on the forum: https://community.openstreetmap.org/t/i-have-been-accused-of-vandalism/128483

I did not destroy anything and even if I did that is not automatically vandalism. Please actually read the linked wiki article. Do you really think that someone with way more mapping experience in his account is going to randomly vandalize?

The layer tag does not imply that the POI are anywhere. It has absolutely nothing to do with that. The POI may have level tags to tell on which floor they are at. How do you come to your conclusion? The layer tag only implies that the building is "over" the service highway. This is needed since the two features intersect. The layer tag does not indicate if anything "touches" the ground or not. Again, please read the wiki about layers.

Settle down a little bit. You don't seem to know what vandalism is. I did not destroy anything or added features that do not exist or anything like that. Please check out osm.wiki/Vandalism to find out what vandalism is.

Of course that is the same building. Check out osm.wiki/Simple_3D_Buildings to find out how building:levels is used.
Also, of course it needs layer=1 because part of that building is overlapping the service way as did the smaller buildings before. Check out osm.wiki/Key:layer to find out how the layer tag is used.

Please check out e.g. Warsaw or Gdansk airport to see that what I mapped is quite common.

Please do not randomly accuse people of vandalism.

Please restore my edits.

just why?

Nein, eindeutig ein Versehen.

rb stands for Regionalbereich
lv stands for Landesverband
plus there are few more

The THW is grouped into those. The tags were documented in the wiki for the relations which were deleted at the beginning of this year. The tags replace the relations.

I deleted them because there is no physical separation and the sidewalks are already tagged to the highway=secondary. They were thus redundant.

Sorry, I got quite confused when I got routed through oneway streets in the opposite direction. Some streets have an additional sign that allows for bicycles to go in the opposite but those that I modified did not. I did not know about the living streets rules. Sorry again. Thanks for correcting my mistakes.

Moin,
nein, das war ein Versehen. Habe es entfernt.

Ja, alles klar. Ich bin nur immer skeptisch, wenn neue Accounts Daten löschen und aus dem Kommentar war es nicht so genau ersichtlich.

Moin c_7,
wieso entfernst du hier die Faxnummer? Laut https://www.thw.de/SharedDocs/Organisationseinheiten/DE/Ortsverbaende/A/Amberg_Ortsverband.html hat der OV eine Faxnummer.

Im Bereich vom THW und der Feuerwehr. Abandoned heißt, dass noch irgendetwas von dem Verlauf zu erahnen ist. Das ist dort definitiv nicht der Fall.

Moin, du hast hier historische Gleise gemappt, von denen gar nichts mehr zu sehen ist. Das entspricht nicht den Regeln im Wiki: osm.wiki/DE:Tag:railway%3Dabandoned

Ich bitte dich daher, die Gleise wieder zu entfernen.

C'est un Space Invader. Le nom est donc correct mais souvent il y a aussi une description dans le nome ce qui est bizarre. Les Space Invaders sont ajoutés par des personnes qui ne savent pas utiliser maps.me.

Dann ist der Umzug wahrscheinlich nicht mehr weit entfernt. Zwei Standorte gleichzeitig wird es aber nicht geben. Noch ist die neue Adresse nicht im Internet zu finden.
