Re: So...
If this is just altitude limits and no fly zones (airports etc) from the GPS, or something more deeply involved I've no idea sorry.
May's government is involved it. That should give you plenty of "idea". The same government who employs rhymes-with-Elmer Fudd.
Altitude limits, airport no fly zones, attitude limits (ie "Drone operator pissed us off by finding a way to capture footage of..."), and also protest limits (not near protests to film bad stuff by the piggywiggies), alleged terror incident limits (so you can film all the fleeing panicking people to your hearts desire, but you can't film that it's just a couple of blokes having a dust-up), and more that even I can't conceive of.
