  • Publication number: 20230049959
    Abstract: An emergency response system provides a map-based interface for a telecommunicator to view information about an incident and coordinate a response to the incident. The emergency response system gathers supplemental data regarding locations and other information that may be relevant in assisting with the incident. The interface may automatically select relevant supplemental information based on the incident and provide this incident-specific information for display on the interface. The user may then select a response on the interface such as a unit to dispatch that the system automatically implements, providing unified information and control for incidents, supplemental information, and incident response.
