How can police analyze the number of crimes that occur and use that information to assign resources effectively? For the Village of Mundelein, IL, the answer was mapping. Because Police Sub Beats are integral to the process of assigning resources, it is important to know how many incidents occur in each. The Geographic Information Systems (GIS) Office recommended mapping incidents on top of Police Sub Beats to see correlations and frequencies at a glance.
The project focused on mapping auto and structural burglaries over the past two years. Locations were overlaid on Police Sub Beats and three maps were created to display data from a variety of viewpoints. One map depicted the location of each incident; a second map showed the number of incidents in each Sub Beat; and a third map displayed the density of burglaries throughout the Village.
Now the Chief of Police can look at the number of incidents per Sub Beat and determine if Sub Beats need to be realigned or if more resources must be assigned. By combining information from dispatch record software and GIS databases, the GIS Office quickly created a trio of maps to help police visualize burglary “hot spots” in the community.
