Crime mapping is a law enforcement tool which allows personnel as well as community residents to represent crimes visually on a map or grid of a region. By organizing crimes this way, law enforcement personnel and the public can identify patterns, areas of concern, and other information of interest which they can use in order to have better police response as well as better informed citizens. Many urban police departments practice crime mapping, and it is common for such maps to be released to the general public so that citizens can stay informed about areas of concern and patterns of crime in their areas. The North St. Paul Police Department takes pride in informing the community of crime patterns and informing its citizens what’s going on in their community.
How Do We Get Crime Mapping Data?
Most of the data that is used in crime mapping and analysis originates from police dispatch. When a call comes in, the incident is entered into the database. The database can then be queried. If a crime is committed, the crime goes into the crime management system. If and when a perpetrator is caught, the incident then is entered into the court database, then, if convicted, the corrections database, and then possibly, eventually the parole database. Data is drawn from all of these sources in order to identify patterns and solve crimes. Community Online Crime Map.
