{ "currentVersion": 10.71, "serviceDescription": "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 the geographic area of all PSAP boundaries within a given 9-1-1 Authority\u2019s geographic coverage area. The PSAP Boundary layer may have one or many PSAP Boundaries contained in the layer.

This layer is used by the ECRF to perform a geographic query to determine the PSAP to which an emergency request is routed.
