  3. Soon, Suddenly, Address Data Will REALLY Matter • In order for the ECRF to work, you have to get your LVF in place! • (Translation: in NG9-1-1, for calls to get routed to the right call center, you have to have good locations for every address.) • And by the way, as you wade into 911, get ready for the acronym storm.

  4. (Partial!) Glossary • MSAG: Master Street Address Guide • ALI: Automatic Location Identification • LIS: Location Information Server • MPC: Mobile Position Center • SIF: Spatial Information Function • ECRF: Emergency Call Routing Function • LVF: Location Validation Function

  5. What GIS Will Need to Provide • Accurate address locations • Points preferable • Ranges on road centerline as fallback • State/County/Muni boundaries • Service boundaries: PSAP, Fire, Police, EMS, etc.

  6. NextGen in NJ: Big Picture • OIT’s Office of Emergency Telecommunications Services coordinates both radio communications and 911 • NG911 implementation requires specialized knowledge • RFI issued a couple of years ago, still insufficient understanding to craft plan • OETS plans to engage a consultant to lay out road map, craft RFP for implementation • Initiative will definitely require support in legislature, but any talk of consolidation gets highly political • (Translation: we GIS folks do have some time)

  7. What To Start Doing Now • Learn about how NG911 works • Start forging relationships with 911 personnel • Build first-cut data sets • Enlist 911 personnel in data maintenance

  8. Address Ranges/Road Centerlines • Enhanced DOT centerlines will be foundation • Web app for maintenance coming soon • Authorized contributors at local level will be important sources • Rapid refresh cycle to get changes into users’ hands quickly

  9. Address Points • OGIS has draft statewide points based on parcel centroids • Pilot project with Essex and Monmouth to explore distributed editing • Will likely add point editing to road app • Ultimate goal is multiple points per address • Standards development at national level

  10. Multiple Points Per Address • Parcel centroid (low-hanging fruit) • Building centroid • Building entries • Driveway entry from road • Sub-addresses • Outbuildings • Apartments, condos, office suites

  11. National Efforts: Roads • NSGIC proposed “Transportation for the Nation,” nationwide aggregation of locally-originated road centerlines • USDOT adopted the idea, developed a strategic plan • MAP-21 Act signed July 2012, includes requirements, funding mechanism for states to submit comprehensive centerline data • NSGIC urging USDOT to include addresses, support for that from (FGDC) National Geospatial Advisory Council • Data model not yet defined

  12. National Efforts: Addresses • Lots of people talking about addresses, don’t yet have a clear direction or momentum • Census Bureau working actively to come up with strategy to do addresses outside of Title 13. Not simple. • URISA/FGDC standard exists for attributes • NENA workgroup developing a standard for spatial data for “structure points” • Very active work group in NSGIC

  13. Summary As far as GIS data and maintenance processes to support NG911, we have a good base, a good direction, and a good idea of how to get there, but lots of details still to work out. Karen Mitchell for Andy Rowan, Director, NJ Office of GIS andrew.rowan@oit.state.nj.us 609-462-6376
