8. CompStat Jack Maple was the Deputy Police Commissioner in New York City for Crime Control Strategies. He created CompStat. CompStat (Computer Statistics) is a dynamic approach to crime reduction, quality of life improvement, and personnel and resource management. Maple co-authored the book The Crime Fighter and inspired CBS’ TV series The District. Cast of The District, the TV series inspired by Maple’s experience.

11. Increasing use of Crime mapping By 2002, At least 13 percent of the police departments in the U.S. are now using GIS to solve crimes, according to the National Institute of Justice (NIJ).

12. Negative aspects The skill it takes to learn GIS is often underestimated. Integrating the mapping into departmental routine requires substantial effort. It is essential to have working computers and programs to use GIS. If the database gets hacked, a virus infects the computer system, or power outage occurs, the GIS functionality decreases.

13. Crime prevention GIS can: Record and map police activity and crime incidents. Identify crime hotspots Understand crime distribution, explore methods, reasons, and trends in criminal activity. Monitor the impact of crime reduction projects. Use maps to communicate to the public crime rates in their area. That guy needs better crime prevention strategies. Chainey, Spencer, Ratcliffe, Jerry. GIS and Crime Mapping. Wiley, John & Sons, Incorporated. 2005

14. Summary There are several additional layers in maps used to fight crime. Choropleth and Pin maps were used before GIS to find trends in crime. GIS can be used to track criminals. CompStat is an effective way to monitor crime. It’s used by police departments in most major cities. GIS can prevent traditional crime and new-type crime. Citizens uses crime map to learn the community safety. The difficulty in leaning GIS applications and the potential for computer failure are negative aspects.
