1 Geospatial Intelligence Applications in Law Enforcement Analysis Gregory Thomas

2 Law Enforcement Analysis Supports Law Enforcement Analysis Supports Crime Prevention  Shows patterns of criminal incidents.  Forecasts community threats.  Assists in the effective deployment of patrol.  Supports community policing efforts.

3 Crime Mapping The process of using a geographic information system to conduct spatial analysis of crime problems and other police-related issues.  Facilitates visual and statistical analyses of crime.  Allows linkage based on common variables.  Helps to communicate results of analysis. (Crime Analysis and Crime Mapping, R. Boba, 2005, pp )

4 Environmental Criminology  Rational Choice Theory  Choices made based on opportunities and rewards.  Crime Pattern Theory  Crimes occur where offender’s space overlaps w/victim’s.  Routine Activity Theory  Opportunities change based on changes in behavior.  Environmental Design Theory  Identify and alter geographical characteristics that contribute to criminal predation.  Crime Prevention Through Environmental Design (Defensible Space, O. Newman, 1972) (See also: R. Boba, 2005; T. Baker, 2005)

5 Geographic Distribution Analysis  Occurrence of activity over a particular geographic area.  Plot events and summarize what it depicts.  Map depicting the flow of activities or services from one location to another.  Illustrates flow chart on a map.

6 Geographic Flow Chart Cocaine Flow to the United States Source: ONDCP, Annual Assessment of Cocaine Movement.

7 Spatial Pattern Analysis  Analyze and correlate data sources.  Create snapshot of crime incidents and related factors within a geographical area.  Look for patterns:  Locations  Distances  Direction  Hot spots
