This dataset represents points where address site data has been collected. These points are an amalgamation of different origin point data translated into a NG911-compliant schema using ESRI's Address Management Solution as a reference for compliance and data integrity.*This dataset requires extensive QA/QC and should not be used as an authoritative, source only for application-testing purposes*

Features in the Hydrology - Line layer are representations of creeks, streams, and rivers for the City of Whitehorse.Data was modeled using the NENA NG9-1-1 GIS Data Template (NENA-REF-006. 2 -202 2 ).Distributed from [GeoYukon](https://yukon.ca/geoyukon) by the [Government of Yukon](https://yukon.ca/maps) .

The Site / Structure Addresses layer represents the location of a site, or structure, or the location of access for the site, or structure, for the City of Whitehorse. Site / Structure addresses may also represent landmarks. Address points have the ability to locate sites that otherwise may not geocode correctly using the road centreline data, areas of unusual addressing, and other areas where the data is available.Data was modeled using the NENA NG9-1-1 GIS Data Template (NENA-REF-006. 2 -202 2 ).Distributed from [GeoYukon](https://yukon.ca/geoyukon) by the [Government of Yukon](https://yukon.ca/maps) .

The Provisioning Boundary layer defines the area of GIS data provisioning for the City of Whitehorse. This boundary must be agreed to by all adjoining data provisioning providers. When provisioning data for an ECRF (Emergency Call Routing Function) and LVF (Location Validation Function) the City of Whitehorse must only include GIS data for their geographic area of responsibility and must ensure the data includes coverage for the entire extent of that area.Data was modeled using the NENA NG9-1-1 GIS Data Template (NENA-REF-006. 2 -202 2 ).Distributed from [GeoYukon](https://yukon.ca/geoyukon) by the [Government of Yukon](https://yukon.ca/maps) .

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](https://yukon.ca/geoyukon) by the [Government of Yukon](https://yukon.ca/maps) .
