Geographic Information Systems

CrimeStat IV

This three day course is designed to introduce participants to a range of analyses that can be completed with CrimeStat IV. It assumes no previous experience using the program, but it does require students have a background in ArcGIS. We will use both ArcGIS and CrimeStat during the course. The course will include lectures, demonstrations and the completion of several exercises that walk students through CrimeStat’s functions. The course is not designed to just teach students how to click buttons in the program. There is a heavy emphasis on teaching students how the skills learned can be applied to problem-oriented policing, crime prevention and implementing evidence-based policing practices.
