If you hear sirens in your neighborhood, you should know why. Crimespotting made this possible in San Francisco and Oakland with interactive maps, e-mail updates, and RSS feeds of crimes in areas that you care about.

We believe that civic data should be exposed to the public in a more open way. With these maps, Stamen started a movement to inspire local governments to use this data visualization model for the public release of many different kinds of data: tree plantings, new schools, applications for liquor licenses, and any other information that matters to people who live in neighborhoods. We welcome inquiries from municipalities and other interested parties who seek to provide their data to the public in a more transparent and sharable manner.
