Hi,

we did something similar with aerial imagery which we presented at the
last FOSSGIS 2018 in March:

There will be other examples as well.

Quite interesting for you will be the Sentinel Copernicus data. There
is also a related "Copernicus Land Monitoring Service", High
Resolution Layer Imperviousness:

For its "Product Specifications", see
