The Fire Response Boundary layer defines the geographic area for the primary providers of response services. This layer is used by the ECRF (Emergency Call Routing Function) to perform a geographic query to determine which Emergency Service Providers are responsible for providing service to a location in the event a selective transfer is desired, to direct an Emergency Incident Data Document to a secondary PSAP (Public Safety Answering Point) for dispatch, or to display the responsible agencies at the PSAP. In addition, Emergency Services Boundaries are used by PSAPs to identify the appropriate entities / first responders to be dispatched. Data was modeled using the NENA NG9-1-1 GIS Data Template (NENA-REF-006. 2 -202 2 ). Distributed from GeoYukon by the Government of Yukon .
