1. NENA Applications of OGC Jason Horning, ENP NENA Data Structure Sub-committee Co-Chair Prsented @ FGDC Standards WG Meeting – September 25, 2014

2. “As we shift focus to the future, GIS will become the hero in the next-generation 911 world and the basis for a lot of what happens. It’s really shifting the role from being a supporting role to being perhaps the heart and soul of call routing and many of the other functions. We’re shifting into this hugely geospatial world.” Sean Petty, Mission Critical Partners

4. The SIF

5. Spatial Information Function (SIF) OGC Standards / Documents Used OWS 7 Engineering Report (OGC 10-069r2) Web Feature Service Implementation Specification (OGC 04-094) GML Encoding Standard (OGC 07-036) Purpose of the SIF “A SIF layer replication interface is used within the ESInet to maintain copies of layers of the master SIF that drive routing and display of maps throughout the system. “ NENA 08-003 Interface between local government GIS databases and NG9-1-1 databases. Modeled after the Replication Feed design of OWS 7 Engineering Report (OGC 10-069r2)

7. The LIS

8. Location Information Server (LIS) OGC Standards / Documents Used OGC 06-142r1 PIDF-LO Shape Application Schema for use by the Internet Engineering Task Force (IETF) OGC 07-036 GML Encoding Standard Purpose of the LIS “A Location Information Server supplies location, in the form of a PIDF-LO (location by value) or a location URI (location by reference).“ NENA 08-003 Provides Device Location: Point, Polygon, Circle, Ellipse, Arc Band, Sphere Ellipsoid, Prism Managed outside of the NG9-1-1 system (telecommunications service providers)

10. The ECRF

11. Emergency Call Routing Function (ECRF) OGC Standards / Documents Used OGC 06-142r1 PIDF-LO Shape Application Schema for use by the Internet Engineering Task Force (IETF) OGC 07-036 GML Encoding Standard Purpose of the ECRF “The NG9-1-1 functional element responsible for providing routing information to the various querying entities is the Emergency Call Routing Function (ECRF). “ NENA 08-003 Given a caller’s location (GML geometry), which PSAP Polygon is the right one? Geometries Used: Point, Polygon, Circle, Ellipse, Arc Band, Sphere Ellipsoid, Prism
