geographic profiling is an investigative tool that can be seen as a strategic information management system to assist police with the large volume of information throughout an investigation. it concentrates its focus on the geographic aspects of the crime and was developed in response to the demands of solving serial crimes. in response, rossmo developed a computerized geographic profiling algorithm called criminal geographic targeting (cgt) which assess the spatial characteristics of crimes. it analyzes the geographic coordinates of the offender's crimes and produces a color map which assigns probabilities to different points for the most likely area of the offender's home base. cgt has been patented and integrated into a specialized crime analysis software product called rigel. the rigel product is developed by the software company environmental criminology research inc. (ecri), which rossmo co-founded.
