Description: The primary use for the PSAP Boundary is to route call/emergency requests for NG9-1-1.This layer depicts the polygon(s) and related attribute information that defines thegeographic area of all PSAP boundaries within a given 9-1-1 Authority’s geographiccoverage area. The PSAP Boundary layer may have one or many PSAP Boundariescontained in the layer. Each PSAP Boundary defines the geographic area of a PSAP that hasprimary responsibilities for an emergency request. This layer is used by the ECRF toperform a geographic query to determine the PSAP to which an emergency request isrouted. An emergency request is routed using the NG9-1-1 Core Services based upon thegeographic location of the request, provided by either a civic address, geographiccoordinate or geodetic shapes as defined in NENA-STA-010 [2][1].
