When I need to map well buildings in a residential area I use in addition to satellite images the oblique low altitude aerial photos. Here are examples of such images, which I produced with the Phantom quad:

Such data fusion provides better understanding of an area. We can see not only buildings' roofs from above,  but also what these buildings are, their height, etc.

An aerial image covers much larger surface than a "street-view" style image. So no need to store millions of photos for a town, as a dozen or two of 4K aerial images would give a good general idea of a place.

The RPAS are becoming lighter (the new DJI Spark is only 300 g), safer, cheaper, with better cameras.

I found so far only one practical way to connect the oblique low altitude aerial photos to the main stream OSM map, - it is via Wikimedia Commons (Wikidata). If you have an idea regarding this field, please, let me know.

Best regards,
Oleksiy
