About the CrimeMapTutorial

CrimeMapTutorial© is a step-by-step tutorial for learning how to do crime mapping using ArcView GISTM or MapInfo ProfessionalTM GIS. Users will get a thorough introduction to most of the knowledge and skills needed to produce daily maps and spatial data queries that uniformed officers and detectives find valuable for crime prevention and enforcement. Users will utilize GIS and police data supplied by the Rochester, NY Police Department.

CrimeMapTutorial can be used for self-learning. Alternatively, instructors can use CrimeMapTutorial in a lab setting by giving short introductory lectures and then letting students work at their own pace, with instructors answering questions.

The package has three tutorials taking approximately six hours to complete in total, including exercises. The best order for learning the material is sequential, but users can do just the tutorial or tutorials of interest in any order.

Users will need to purchase and install ArcView GIS Version 3.x or MapInfo Professional 5.5 or higher, if one of those packages is not already on their PC.

Crime Map TutorialAbout the Logo

The maps that are produced in a GIS are mostly made up of points, lines, and polygons (boundaries for closed areas formed by connect-the-dots lines) - that's why these elements were included in the logo.


The authors are grateful to Dr. Nancy La Vigne, former Director of the Crime Mapping Research Center. She recognized the need for GIS training materials explicitly designed for law enforcement, and funded CrimeMapTutorial. Thanks also go to Chief Robert Duffy, Captain Bruce Philpott, Lt. Joe Sturnick, Lt. Michael Wood, Sgt. Tony DeBellis, Sgt. Glenn Hoff, Officer Jim Lanzillo, Jeff Cheal, and Dave Larrabee of the Rochester Police Department, and Carol Schmitt and Andy Roberts of the Rochester Bureau of Data Processing for providing police data and many ideas on crime mapping used in this tutorial. Commander Kathy McNeilly, Commander Bill Valenta, Officer Darlene Stevens, Officer Deborah Gilkey, and Officer Maureen Noszka of the Pittsburgh Bureau of Police, and John Staudacher, John Schultie, and Eric Miazga of Pittsburgh City Information Systems provided additional valuable crime mapping ideas. Lastly, the authors are grateful to Geographic Data Technology Inc. for contributing its Dynamap/2000 street centerline map for Rochester, New York.

Mapping and Analysis for Public Safety Program

The Mapping and Analysis for Public Safety Program (formerly the Crime Mapping Research Center) at the National Institute of Justice was established in 1997. The goal of the program is the promotion, research, evaluation, development, and dissemination of GIS (geographic information systems) technology for the spatial analysis of crime and criminal behavior.
