Did you mean this to be landuse=construction ?
This isn't a single building is it?

This can't be a single building... right??? should this be landuse=construction ?

Hello, creativebeg, you have tagged a very large area as a single building. Did you mean to tag this as a contruction site? way/1551801373 it tagged as building=commercial, but the shape and size I think seems like you meant it to be a landuse=construction
I see you have made a few other like this in the area. Can you please confirm and fix if I am correct?

I think this is a broken duplication of relation/13994662
I personally would delete it.

I'm not sure I understand your changeset comment. You created the admin_level=1 relation. Why is relation/20658903 not closed and why is an urban boundary an admin=1?

This changeset caused many duplicate buildings. Please alter your process to make sure that you are not duplicating buildings.
eg. you duplicated way/1543356262 with way/1543995507

Hello Magritte, I think there might be some confusion here about how to represent buildings in OSM. Generally buildings are defined as a single shape to depict the footprint of the building. If there are parts that you want to detail then those should be tagged as building:part=yes. Some of the edits here have buildings overlapping other buildings.

It looks like the building part 1499996508 has an invalid geometry. I think it is appropriate to delete this part?? This part when you try to convert it to parquet and use the ST_ISVALID function it crashes.

I think you meant
name:zh-pinyin, not name:zh_pinyin
name:zh-zhuyin, not name:zh_zhuyin

Hello. It looks like you created a self intersection in the relation/11042185. Can you please try to fix it.

Oh, Now I think I know what happened. There are/were a bunch of address node that I converted into the buildings. It looks like the addresses had names and those names became the name of the building. I think most of the names of these buildings should be removed. Some of them are addresses and some of them are the local name of the house.

Must have been an oversight. Definitely didn't mean it. I just fixed the name to remove the street name and the owner's last name

Hey KindredCoda... Thanks for adding the GGB building structure! I'm wondering if a type=building relation would be better here. Then all the parts would be role=part. See osm.wiki/Relation:building
The way it is now as a multipolygon and all the parts that overlap each other as role=outer doesn't really work very well because "Generally, the multipolygon relation can be used to build multipolygons in compliance with the OGC Simple Feature standard (Graphical examples of OGC validity). Anything that is not a valid multipolygon according to this standard (e.g., polygons with intersecting rings) should also be considered an invalid multipolygon relation, with the notable exception of touching inner rings (see below)."

Just a thought - I don't think it would be hard to convert it - you've done all the hard work already.

This caused many duplicate houses. Please verify that your conflation process does not lead to duplicate buildings.

Hello CAT Fijn, please don't add the address of a house to the name. residential houses generally don't have names. add an address if you would like to. Also, please don't add buildings on top of other buildings.

adi04, you seem to be duplicating buildings that are already on the map. I see you are relatively new, so this is probably a mistake. I'm deleting the duplicates... but please review the wiki about adding buildings to the map. No need to duplicate geometries.

This is obvious fantasy and not based on reality. Please revert this changeset.

Why did you make buildings into diamond shapes? See way/531354067

It looks like this edit broke relation/13737951. Can you please take a look and see if you can fix it? I'm seeing that this multipolygon has an unclosed part.

Just wondering... are the "names" that you are assigning actually addresses? Or are they actually the name of the buildings? Just wondering if these should actually be address = <blah> ?
