Maybe it is only cool to me, but the state has photographed the whole country at 12.5 centimetres per pixel.

ČÚZK Ortofoto. I deployed it as the satellite layer of our map and it has been running for half a year without a problem. Now I also use it as the fallback image for venues where we have no photo. Instead of a placeholder you can at least roughly see what the place really looks like.

PS: It was not made for the public. It was made so rapeseed subsidies couldn’t be faked. They update it every two years.
