Hello. Thanks for mapping.
A few issues.
First, solve the issues shown by the issue triangle of IDeditor before you upload your work.
Your mappings are not that accurate as we might expect. Buildings not squared. Building nodes connected to other buildings or roads.

Keep an eye on complex buildings, Especial the high rise (multi story) buildings and buildings which shows their sideviews as well. Check this footage how to map these buildings

Hello. Thank you for mapping on this project.
Please tag buildings as building=yes because that is standard for OSM tagging of building. From the Imagery we cannot see what the purpose is of a building.
Best regards and keep mapping

Hi. Another issue
Images are taken under a certain degree so you see both the roof and a siding.
A gable roof has a bend at its highest point. Map this roof as a single rectangular object because, when viewed from directly above, the roof is rectangular.

Please pay attention to the next summarized issues. (see attached document with examples for more info)

All issues shown by the error triangle should be solved before you upload your mappings.

A: Inaccurate mapping.
B: Overlapping buildings.

C: Collecting adjacent buildings and mapped it as 1 building.

D: Connecting Nodes to other features.

E: Buildings not squared or rounded.
G: Included the shadow of the building.
High building(s) incorrect mapped.

Hello. Thanks for mapping.
About mapping and tagging highways.
A schort local connecting road between 2 other roads is never a secundary highway. At best an unclassified highway.
Check the wiki about tagging highways.

Do not add a layer to a building to hide an error. Just place the building on the correct place, or adjust the road a bit.

Hello again.
These mappings are far below par as well.
See my comments on your mappings.

Hello again.
Also, these mappings are very inaccurate.
Buildings need to be tagged as building=yes. Not building=house !
Best regards

Hello.
Very inaccurate mapped.
Map more precise and square each rectangular building please.
Best regards

Hello . Thanks for mapping.
A remark. You mapped a narrow white spot close to a mapped building as a building. What you mapped, was a sidewall rather than a building itself
Check this footage about mapping of buildings with visible sidewalls.

Keep an eye on complex buildings Especial the high rise (multi story) buildings and buildings which shows their sideviews as well. Check this footage how to map these buildings

Hello. Thanks for mapping.
Please do not map a whole plot as a single building. Just map each building individually.
Best regards and keep mapping

Hello. Thanks for mapping.
You tend to oversize the round buildings.
Please stay within the roofline.

Hello. Thanks for mapping.
Please square each rectangular building with the Q key while still selected.
And, be more precise in mapping round buildings. You tend to oversize these.

Hello. Thanks for mapping.
I review your work because I was validating on the 27165 project and noticed your (sorry to say) poor mapping quality. Here the same. Connected nodes to eachother. Buildings not squared
Please improve your mapping skills !!

Since it takes more time to adjust your mappings, I removed them, so another mapper can map them from scratch.
Please solve also the issues shown by the issue triangle of IDeditor before you upload your mappings

Best regards and keep mapping!
