Public Safety plays a crucial role in the day to day activities of Village of Deerfield. The Village of Deerfield Police Department believes that their daily activities help support a safe and vibrant community. A crucial operational aspect of the Police Department is conducted 24 hours, 7 days a week, all year long is Dispatch. The Dispatch Department and the highly trained officers are responsible for receiving and dispatching appropriate resources for all emergency and non emergency activities in the Village. The major focus of their operation is to respond to all calls placed to 911, dispatch resources, and relay information to officers in the field. Mapping is a major factor in this operation from locating the call in dispatch and to reporting location information to the officers in the field. Without highly accurate, detailed, and up to date mapping data would create a major challenge in the emergency response cycle.

The Dispatch Department uses a very advanced Computer Aided Dispatch System or (CAD). This system handles all aspects of emergency dispatch from the initial call to proper resource dispatch. The system also performs very important incident reporting activities which the Police Department uses to review and analyze their activities. The common component in all of these functions is location and mapping.

The Village of Deerfield GIS department works both with the Police Department and their CAD vendor to load and update all mapping the data needed to support the system. This includes providing highly accurate mapping data developed by the Village of Deerfield to the CAD vendor for loading into their system. The provided mapping data includes extremely accurate street centerline files, address point locations, all district and beat layers, common places layer, and highly detailed aerial imagery. This mapping data is also maintained by the Village of Deerfield and is updated by the GIS Department reducing the overall cost of not relying on a third party vendor and lesser quality of data. This also ensures the mapping layers are as current as possible and makes it possible to update and refresh changes when needed with minimal effort.

In summary, every phone call to dispatch uses some form of the provided data to record and assist Dispatch and Officers with the most up to date and current information. The data is also indirectly consumed by the public in large including Village residents because they benefit in a highly efficient and accurate system when consuming E911 services.
