Building GIS Master Data to Support Next-Gen 911

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