CRJU145-Justice Information Systems

Week 6 Lecture

Geographic Information Systems (GIS) and mapping technology is not a new tool. Dating back to the 1800’s, authorities used mapping to detect and track the source of a cholera outbreak in London that took hundreds of lives. GIS technology is used in a number of applications and this module discusses the adaptation to crime mapping.

GIS aids crime analysis by:

  • Identifying and highlighting suspicious incidents and events that may require further investigation
  • Supporting pattern and trend analysis across multiple jurisdictions
  • Enhancing the implementation of various policing methodologies to reduce overall crime and disorder
  • Integrating traditional and nontraditional law enforcement data to improve overall analysis
  • Educating the public with visual information to clarify crime concerns and enlist community action
  • Providing tools and techniques to capture crime series and forecast future crime occurrences

Mapping Location of Criminal Activity

  • Law Enforcement agencies can track criminal activity and target detection, prevention, and apprehension in these “Hot Spots” of crime.
  • Focusing police resources to these “Hot Spots” can drive crime away from the high crime areas.

Mapping Locations of Criminals

  • Knowing where criminals live can be used to predict the movement of crime.
  • Allows the courts and corrections departments to inform the public

Mapping Location of Resources

  • Keeps track of what law enforcement resources are in which areas, allowing quicker response times to calls for service
  • Informs the public of social service resources to aid offenders in rehabilitation
