In a fully operational Next Generation 9-1-1 system, GIS is the core component in determining how a 9-1-1 call is routed to the correct public safety answering point (PSAP). To route calls correctly, NG9-1-1 includes multiple standards around minimum data quality requirements for GIS data provisioned into the Emergency Services IP Network (ESInet).

For current 9-1-1 systems a 98 percent accuracy rate is far better than good, but for the NG911, 98 percent isn’t quite good enough. But, how do you determine if your GIS centerlines and address points is ready to support the critical path of emergency response?
