The Journey to Next Generation 9-1-1: A Spotlight on Your GIS Data



Overview

• What is GIS for 9-1-1?• How does GIS function today in 9-1-1?• How will GIS function in NG 9-1-1?• Steps to take, plan for• What are risks of inaccurate data?



GIS data for 9-1-1



Benefits of GIS data in 9-1-1

• Location, Location, Location– Locate address, coordinates, physical location on earth’s surface– Provides reference location for dispatch on map– Accurate GIS data reduces risk by providing improved location

information– What if location information in GIS data is incorrect or

incomplete?• Incorrect routing of emergency responders• Increases response time• Lives in jeopardy – every second counts

What is Next Generation 9-1-1 (NG 9-1-1)



Location Info in NG 9-1-1

• 123 Main Street• -78.3456, 40.2345• 192.10.1.123

• Voice• Text• Media – Photos, Video



GIS in NG 9-1-1

• GIS plays crucial role in NG 9-1-1 call routing• ALI and MSAG become decommissioned in NG 9-1-1 i3• GIS data replaces ALI and MSAG data• Accuracy of GIS data is paramount• Shared data – coordination• 9-1-1 authority is responsible for the data• Location is delivered with call • Location is pre-validated using GIS data

Accuracy

• GIS data used for call routing• Accuracy of data will determine correct routing of call

• GIS road centerlines, address points and jurisdictional boundaries all become focus of emergency routing databases

• What can you be doing to prepare GIS data?• Synchronize GIS with MSAG and ALI

• NENA 71-501, Version 1.1, September 8, 2009

• Completed address points layers• Edge-matching boundaries, centerlines



Data Integrity

• Spatial accuracy – visual verification• GIS topology – gaps, overlaps, connectivity• Features delineated between community and ESN

boundaries• Complete information for each feature

– Road names, addresses, ranges, community, ESN

• Verify for address range overlaps or gaps, parity issues• Check for duplicate addresses, road names• Verify addresses fall within existing street segments



Edge-matched boundaries



Maintenance

• Data maintenance is ongoing process• Must have maintenance plan• Data maintenance must follow proper 9-1-1 standards• Continue to synchronize databases/layers• Coordination with jurisdictions/departments

• Road names, new addresses, boundaries

• Investigate errors, make updates



Standards

• Standards become paramount with NG 9-1-1• Having the correct information collected in the correct format • To foster regionalization of data/sharing of data• To integrate with NG 9-1-1 databases• To improve accuracy/maintain integrity• Interoperability with other systems• Addressing standards, GIS data design standards

• Other GIS layers in NG 9-1-1 – Railroads, Hydrology, Parcels, Critical Infrastructure

All play part in routing call to correct location



What risks exist for your agency?

• Discrepancies, inaccuracies across datasets remain• Data is not ready for applications on NG 9-1-1 network• Data is not ready to be regionalized – lack of standards• Data maintenance processes and policies not in place for

NG databases

Inaccurate data is a risk today and in NG 9-1-1

Need to be thinking about the data in parallel with the design/implementation of the network
