[citation][nom]Snipergod87[/nom]They arent invading your property, anybody can view your property from above legaly. Its well within anyones rights to do this.[/citation]
But taking photos and then distibuting them? There are already cases of aerial photography companies being sued because even though the air itself is public space then taking a photograph into someones private property invades their right to reasonable privacy.
If you take a photo me walking down the street I am not protected, but if I sit in my garden with a 20ft wall around it and you get a ladder, poke a camera over the top and snap away I will sue you, same applies for another taller property nearby, a helicopter or a kite.

My favourite bit is this
Intrusion of solitude. Home, seclusion, private place, a place out of public view, reasonable expectation of privacy. similar to trespass if the intrusion would be highly offensive to a reasonable person.
Inside a 20ft walled garden could be reasonably expected to be out of public view and your viewpoint being extended by artificial means has legality issues relevant to the country in which it takes place.
India for example requires a permit to be applied for.
England has it's own privacy laws.
The European Convention on Human Rights has plenty to say.
Just because in the USA you can be a pervert and take pictures of people sunbathing nude in their private back gardens, the law doesn't make it right.
