Geospatial Intelligence Applications in Law Enforcement Analysis Gregory Thomas
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.
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 )
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)
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.
