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

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

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
