To get more into Django programming I'm planning to create a google maps mashup, which finds routes from A to B but avoids streets/junctions that cross public surveillance cameras' perspectives. Therefore I will create a database (probably Postgres based, because of its GIS capabilities) containing
surveillance type (surveillance camera, speed camera, road charge camera, etc.)
geo position
timeout (used mainly for speed cameras)
This data will then, of course, be editable freely by the users. To start, however, I will need some data to get running. Is there any such publicly available database containing (possibly approximate) geo-position of surveillance cameras?
