Hello. Here you draw an empty field as a building.
You have to look for proof that it is a building, like a shadow. No shadow? no building.

Please be more accurate when drawing alongside rooflines. You regularly just draw a rectangular, ignoring corners of complex buildings.
Quality prevails above quantity

Hello.
You mapped 2 warehouses as 1 building.
You can clearly see that it are 2 buildings. Map them as 2 buildings

Hello. Please square each rectangular building after drawing it by pressing the Q key while the building is still selected ! Make it a habit.

We welcome you as a new mapper.
Thanks for your contribution to this project.
This changeset is reviewed by a Global Validator to check that the tasks have been mapped in accordance with the quality standards of HOTOSM.
We cannot expect from a new mapper that he/she delivers high-quality mappings from the start, so we offer some guidance.
Please pay attention to the next summarized issues. (see attached document with examples for more info)
-------------------------------------------------------------
A: Inaccurate mapping.
E: Buildings not squared.
High building(s) incorrect mapped. See par 20 chapter About Buildings ( you can see the sidewalls here as well, so adjust the mappings)

Explanation can be found in this document what might be helpful to strengthen your mapping skills

Hello. Thanks for mapping.
Please map buildings not as multipolygons. Just as single building.
Multipolygons are used to map courtyards within (large) buildings.
Best regards

Hello. Thanks for mapping.
a few remarks.
Buildings should be mapped as building=yes. nothing else.

A remark about the way high rise or multi-story buildings are often mapped
On the imagery, you see both the roof and a sidewall (with multiple floors)
The imagery is taken under a certain degree and shows you the height of a building.
Don't map both the roof and the sidewalls as 1 building.
Draw just the rooflines as a building and move it to the building's footprint.
See this clip.

Hello. Thanks for mapping.
The instructions are to map buildings and roads. Please focus to that.
You mapped land use objects and introduced many errors by doing that. Please just map buildings and highways.
Don't connect nodes of objects to other objects. These are errors which have to be solved,
Best regards and keep mapping

Hi again.
Due to the fact that most buildings are poor mapped, most of your mappings will be removed and need to be mapped according to the mapping guidelines.
Sorry that we have to do this.
Best regards and improve your mapping skills please.
