Emergency Call Taking and Dispatch

How GIS is Used in Computer-Aided Dispatch/E-911

The following core capabilities can be enhanced using GIS technology enabling staff to more effectively carry out all types of tasks for supporting every kind of public safety emergency.

and Analysis

Planning and Analysis

GIS technology provides the capability to proactively map and analyze historical emergency 911 calls to better anticipate where law enforcement, fire/rescue personnel, and emergency medical services are most likely going to be needed. Emergency dispatchers are better able to ensure proper service coverage and quicker response times.

Data Management

Emergency Dispatchers require access to many sources of data that are often maintained in disparate databases. GIS provides an integration platform for the management of data from multiple systems by fusing on the lowest common denomination-location. Spatially storing and maintaining data provides an effective method for emergency dispatchers to quickly access and assess information visually in the context of a map.

Field Operations

Most computer-aided dispatch (CAD) systems link with in-vehicle mobile data terminals used by fire/rescue and law enforcement. Mobile GIS provides the ability for first responders to access vital incident information as they are responding to a call. Responders can quickly locate information about the current event as well as historical information about previous incidents that have occurred that given location.

Situational Awareness

A GIS map displaying relevant GIS data (critical infrastructure, incident locations, hydrant locations, station locations, etc.) integrated dynamic event data (alarms and sensors, cameras, traffic, incidents, etc.) provides emergency dispatchers with comprehensive, real-time understanding of an incident. The increased capability to rapidly process and disseminate information results in enhancing the protection of people and assets. GIS also provides a flexible information exchange platform to rapidly integrate new/additional information across centralized and remote operating environments.
