Thanks for your contribution to this project.
This changeset is reviewed by a Global Validator, during the validation process.I noticed that you are a new mapper. Welcome to HOTOSM.
We cannot expect that you are already familiar with all issues around mapping. Therefore, I inform you about the most issues,
Please pay attention to next points:
Buildings are in general rather rectangular. Just 4, 6 or 8 nodes are sufficient.Please map each building accurate over the rooflines.
Square each rectangular building with the Q key.
Nodes of buildings may NOT connect to other buildings or features.
The shadow of a building is not a part of the building.
Do not cluster buildings. Each building need to be mapped individually.

Hello.
About mapping of tall apartment blocksMapping of tall buildings differs from standard buildings. Because the imagery is taken at an angle, you see both the rooflines and also the side of a building.
How do you map such a building?
Map over the rooflines and lastly slide the mapped building to the footprint.
Please adjust wrong positioned buildings as well
This video shows how that is done.https://drive.google.com/file/d/1V5-bADsYiffCD9bo6l64YOdTvmKqMGry/view?usp=share_link
And.... don't forget to square each rectangular building.
Best regards and keep mapping
