Display Field: DSPLAYNAME

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: The PSAP (Public Safety Answering Point) Boundary layer is a polygon that defines the geographic area that a PSAP or 911 Authority has responsibility for emergency service requests. In an NG9-1-1 environment, the PSAP Boundary layer determines the PSAP that should receive a 911 call. This layer is used by the ECRF (Emergency Call Routing Function) to validate the location of a 911 call and perform a geographic query against the PSAP boundary layer to determine the PSAP that is responsbile for the 911 call.This layer represents the PSAP Boundary layer that is provisioned to EGDMS. It is clipped to the provisioning boundary to remove any portions extending beyond the provisioning boundary. Any gaps between this layer and the provisioning boundary have been filled with neighboring PSAP data. As a result, this layer contains both Fairfax and non-Fairfax data. The source non-clipped layer can be found in the NG911_BOUNDARY feature dataset which is where feature edits should occur. This layer should not be edited directly.This layer should be updated in coordination and agreement with neighboring PSAPs to ensure that data is seamless across borders. This layer should not contain unintentional gaps or overlaps. Gaps and overlaps have the potential to result in a delay in emergency response due to the inability of the ECRF to use the PSAP boundary to query in areas of gaps (area of no coverage) and/or overlaps (duplicate coverage).Contact: Fairfax County GIS DivisionData Accessibility: Publicly availableUpdate Frequency: As needed and dependent upon EGDMS provisioning schedule. This layer should be updated with source data only prior to provisioning to EGDMS. Creation Date: 01/2020Layer Name: GISMGR.EGDMS_PSAPDataset Name: GISMGR.NG911_BOUNDARY_EGDMS
