HI, Gábor.

This is considered a city in Portugal, and I live 20 km from it. Of course is not big in terms of other big cities in Europe and elsewhere, but it has a considerable size for our standards.
Just to give you an example, you mapped hundreds of hotels as residential and also the basilica area as residential. Also, there are big parking areas, schools, museums, religious areas and small farming lots that were mapped this way.
Unless you intend to exclude all these areas and map this correctly in the near future, I don't see how this is useful for the map.
Please, consider reverting this edit.

Cordially,
António.
