The idea behind this map is for when someone sees a police car go by with the lights on -- they can visit our website and see the incident on a map.
I made 3 flavors of this app. The first is a widget for the Police Home Page, the second is the same map with a list of incidents below it, and the third is a BIG map with a list of incidents.
I'm considering also making an iPhone version. This wouldn't be a native app, but a web app formatted for the device.
I used the 911 Dispatch Incidents (geoRSS) feed and filtered it for Police Incidents for the past 6 hours.
