Hello. Thanks for mapping on this project.
Please do not tag paths/highways inside residential areas as a track. Look where a track is to be mapped on the highway wiki.
Best regards

Hello. Thanks for mapping on this project.
You regularly cluster buildings!

The imagery on Bing show what appear to be a cross-hatched roof/covering across both that building and the one adjacent to it.

In Mapbox, the building does not appear, but some smaller buildings are evident.

Hello. Thanks for mapping.
