Soon suddenly address data will really matter

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

(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

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

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

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

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

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

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

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

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


Summary

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.
