Can someone start an indiegogo to fund an independent photographer to take high-resolution photos of every utility pole in Seattle?? And then crowdsource inspection of them to identify the cameras?? I would surely contribute and participate.
Or crowd-sourcing people to contribute photos from their neighbourhood and whenever they're out walking around.
A mobile app which:
a) captures GPS location and a photo upload
b) browse pictures like Tinder (with high-res zoom) and upvoting/commenting on ones you think are likely
c) browse (likely) utility poles near your location
