Crime Mapping

Crime mapping is a process by which raw crime data, provided by a law enforcement agency, is geocoded on a map.

The geocoding process takes the location from the raw crime data—like an address or latitude/longitude coordinates—and automatically plots the location on a map.

Crime mapping, provided by, does not geocode the exact address of crimes, in order to protect the privacy of victims. So, the crime maps that appear on the website, are geocoded to the block level. (i.e., “214 Elm St.” would appear on the crime map as “200 block Elm St.”)

Along with the locations of crimes on the crime map, provides the type of offense that occurred, along with the date and time. In addition, many police agencies choose to provide the public with even more crime information, like details of the specific crime. Some agencies also choose to show the location of registered sex offenders on the crime map. These are often accompanied by a photo, along with an exact address and link to a local or state online sex offender registry—for more information.

Public-facing crime mapping allows members of the community to stay informed about crime in their neighborhood and provides police departments with an informed and more vigilant public.
