This is an incredible picture. I wonder how they did it. I don't think any camera could capture such detail, but making it in parts would reveal some issues with shadows, right? (since they wouldn't reflect one exact moment)
Nevertheless, i'm not sure if this is legal. The reason why satelites can't take pictures with too much detail is because it could be interpreted as invasion of privacy, afaik.
Imagine if there was someone sunbathing nude on the top of a high building. (yes, if that person was doing that, they probably WANTED to be seen, but you know what i mean)
