Service Description: Since 2015, the Public Service Communication Board, VITA Integrated Services Program staff, and staffs from public safety answering points (PSAPs) have been planning and implementing the deployment of Next Generation 9-1-1 (NG911) for the Commonwealth. Transitioning from the legacy telecommunication network provides numerous benefits and flexibility looking towards the future. As the emergency services internet protocol network (ESInet) is deployed, geospatial call routing uses geographic information system (GIS) data and the 911 caller’s location information to identify which PSAP will receive the call. The process of geospatial call routing relies on the civic address layers (address points and road center line maintained by the localities) and a GIS layer representing PSAP boundaries for the operations area for each PSAP. The PSAP boundary file must ensure that every square foot of the Commonwealth is assigned to one and only one PSAP. There can be no gaps or overlaps. PSAPs sharing boundaries with neighboring states must also meet this same rigor to ensure efficient and consistent delivery of every 911 call initiated.

Subject: The intended use of this data layer is for publishing a PSAP polygon as deemed mandatory by the National Emergency Number Association (NENA).
