Hi there, thanks for the reply.
I thought that as well but on the 21st of January update they revealed that they used a data provider for their UK update.
The Bing Maps team is working hard to make this happen and the data provider, Bluesky, is helping as well.
I do not know what price Microsoft are willing to pay, and maybe developers for paid sceneries are looking here too and can get ideas.
I believe local fans can surprise even the largest companies with such info.
Cheers
