Please use the changeset comment field to describe what you changed and why; for example, "added taxiways and grass areas in airports." More examples here: osm.wiki/Good_changeset_comments Also, please save your changes in one area before moving to another, to keep the changeset area small.

…for the roofs that still exist, anyway (I was looking at old imagery)

Standalone roofs can be mapped with building=roof. That would be appropriate here.

The "picnic site" feature preset (tag tourism=picnic_site) is meant for areas with room for multiple groups, not just a single table. For that, a "picnic table" (tag leisure=picnic_table) on a node is enough.

Welcome to OpenStreetMap! Please use the changeset description field to describe what you changed and why; for example, "added the name to a religious building." There are more examples and guidance here: osm.wiki/Good_changeset_comments

Thanks for contributing to OpenStreetMap! In the future, please save your changes in one area before moving on to another; this keeps the changeset to a reasonable size.

man_made=chimney is for large, industrial chimneys, not individual houses: man_made=chimney Private backyards generally shouldn't be micromapped, to protect people's privacy: osm.wiki/Limitations_on_mapping_private_information

The name:etymology:wikipedia and operator:wikipedia you added don't match the name:etymology:wikidata and operator:wikidata that were already there

What did you align to? Buildings were imported from the city and are assumed to have accurate alignment. Otherwise they'd be offset from the rest of the city. Why did you remove so much landuse? Why did you tag the area surrounding the parking garage as a parking lot?

Thanks for contributing to OpenStreetMap. OSM is a service that's used by a number of products, apps, and services, and as such it can't make concessions for any one particular app. If "Goodtime Bar Run Club" is a physical place that exists at that location, then the node should include tags describing what type of place it is. If it's not a physical place, then it shouldn't be included in OSM.

Welcome to OSM! The leisure=fitness_centre tag would mean that this building *is* a fitness center, not that it has one. The fitness center should be added as a separate node within the building outline. Also, office=property_management is a better tag for leasing offices than office=estate_agent. The tourism=hotel it had before was also wrong though, so thanks for finding it and fixing it!

These last few changes were made with Esri, not Bing, whoops

Thanks for contributing! Be careful accepting fixes that the editor recommends—they aren't always correct! In this case I would say that it's better to leave landuse disconnected from buildings where possible, even if it results in close points.

Hello. Please save your changes in one area before moving on to another, to keep the changeset size small. Also, please use the changeset comment to describe what you changed and why; "changes" is not adequate. See osm.wiki/Good_changeset_comments for more examples.
Cześć. Proszę zapisać zmiany w jednym obszarze przed przejściem do innego, aby rozmiar zestawu zmian był niewielki. Użyj także komentarza do zestawu zmian, aby opisać, co zmieniłeś i dlaczego; „zmiany” nie są odpowiednie. Więcej przykładów znajdziesz na osm.wiki/Pl:Dobre_komentarze_zestawu_zmian

shop=chemist and amenity=pharmacy are two different feature types. The main store is shop=chemist and within it is a pharmacy counter, amenity=pharmacy. It was correct for them to be separate.

It's proper to duplicate tags across the building outline and relation, since not all data consumers support building relations. See osm.wiki/Simple_3D_Buildings#Building_outlines

OpenStreetMap is a map of objects that exist in the real world. Please don't add things that don't exist.

When you merge two objects, double-check that all of the merged tags are still correct. Many of the objects in this change now have duplicated names. Additionally, it isn't always necessary to merge a PoI and a building.

Welcome to OSM! The building=* key is meant for what the building was built as; if it was built as a house but re-used as an office, it should be "building=house". See osm.wiki/Buildings . In these cases it might also be better to map the business as a separate node. Also, "building=detached" is for houses that are not connected to other houses. Sheds should use "building=shed". See building=detached
