| 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. |
