Cops and Computers

There's an interesting article available from the Police Foundation in PDF that suggests geocoding NCIC and NBIRS data.

NCIC is the database system used to check for outstanding warrants and NBIRS is what the FBI uses to compile its annual crime statistics.

Geocoding is associating an event with a location through a geographic system, like latitude and longitude . A map datum is a way of gridding the world. Latitutde and longitude is the best known map datum, but there are over 200 of them. UTM is the only other one I'm really familiar with.

I think geocoding NCIC and NBIRS is a good idea. A geocode is a useful bit of metadata.
