I've also been working on a big project for the last year or so, it's a fantasy siren map for the UK if they had a national warning system today. Locations are strategically placed at locations of mobile phone masts to use as an alternative and based on what type they are depends on the type of mast. I know its random but, i thought it was a nice way to make it as realistic as possible. I've also included existing siren locations too. Enjoy!
