Great source of geographic and other data.

Can use it for mashups or, you can push beyond mashups to creating topic maps.

For example, plotting all the crime in an area is a mashup.

Interesting I suppose for real estate agents pushing housing in better neighborhoods.

Having the crime reported in an area and the location of crimes committed by the same person (based on arrest reports) and known associates of that person, that is starting to sound like a topic map. Then add in real time observations and conversations of officers working the area.

Enhancing traditional law enforcement, the most effective way to prevent terrorism.
