Next Generation 911 call delivery

Next Generation 911 (NG911) requires accurate, authoritative GIS data to validate caller locations and dispatchable addresses prior to emergency calls being placed, and when emergency calls are routed to the most appropriate public safety answer point (PSAP). Using ArcGIS to maintain mission-critical location data for NG911—including site/structure address points, road centerlines, and service boundaries to support emergency call routing and location validation solutions—is essential.

ArcGIS enhances NG911 call delivery

Create and manage addresses

Addresses are essential to delivering NG911 calls. Caller locations and dispatchable addresses are validated against authoritative GIS data, and that same data is used to route NG911 calls geospatially to the most appropriate PSAPs. As addresses change, NG911 systems must be updated as soon as possible to ensure 911 calls are routed correctly.

Improve data quality

Ensure GIS data is highly accurate and up-to-date to support NG911. Quality control checks using ArcGIS ensure that data, when maintained and aggregated, remains error-free. GIS-based workflows collect data errors upon discovery and remediate them quickly.

Share NG911 data

Share your GIS data with neighbors to support aggregation and provisioning to NG911 systems. Collaboratively remediate data issues across jurisdictional boundaries. Eliminate data silos by sharing your locally-authoritative data with other stakeholders, users, and anyone that can benefit from your true addressing system of record.

Leverage 3D digital twins

Calls to 911 are placed inside buildings and outdoors. Create elevation-aware, 3D digital twins of the world to more accurately determine caller locations using Z-axis data, and prepare for even more precise NG911 call routing.

Innovate with Esri partners

Esri partners that provide originating services, NG911 services, NG911 Core Services, analytics solutions, and more use ArcGIS to connect directly to locally-authoritative GIS data and caller location information. This enables NG911 emergency call routing to PSAPs and can help you uncover patterns, trends, correlations, and relationships.
