Well this sounds exactly like the project I ran for the local Pirate Party during Slovenian elections - nadzorovan.si ("you are monitored" in Slovenian). You can see the map of cameras here: http://nadzorovan.si/zemljevid http://nadzorovan.si/zemljevid (we targeted the capital city center for coverage). Anyway the original hack was simple - you use your normal camera with geotagging enabled (and a sports app running in the background for better GPS coords) and take pictures of cameras. Activists than sent it to me, I ran it through a basic PHP script that resized the images, stripped the EXIF data and constructed a JSON that was displayed on a map. We upgraded it to the current status - nadzorovan.si - a year later but due to time constraints have been unable to finish the mobile apps that simplify the image taking and upload experience and enables us to incorporate non-Pirate activists. The code will be open sourced (it kind of already is, it just isn't on github) and the dataset is entirely public. We plan to restart the project in the spring. There are a whole host of issues with a project like this - if anyone's interested I can go into details. I should note the project was very well received in the public.
