Preparing for Next Generation 911 Deployment
/CLIENT: City of Franklin
LOCATION: City of Franklin, Virginia
CHALLENGE
Advancements in communications technology have necessitated the transition from analog 911 systems to a nationwide digital network - Next Generation 911 (NG911).
Before the launch of Virginia’s NG911 solution, the local Public Safety Answering Point (PSAP)’s legacy tabular and GIS datasets must meet a 98% match. To meet these requirements, the City of Franklin sought GeoDecisions’ assistance.
SOLUTION
To assist the City of Franklin, GeoDecisions migrated the city’s address and road centerline GIS datasets to a National Emergency Number Association (NENA) compliant public safety standard through a variety of processes. Our team reviewed the existing GIS data for errors such as misspellings, address range disparities, and other attribution issues to create a standardized dataset. Spatial cleanup was required to ensure there were no overlaps, gaps, or breaks within the City’s road centerline data, as this layer would be used for routing during emergency response. In some cases, GeoDecisions’ professionals conducted in-field address verification to review data for accuracy.
Once the data met the NENA standards, Franklin’s GIS was compared to the legacy tabular Master Street Address Guide (MSAG) and Automatic Location Identification (ALI) datasets to identify and reconcile discrepancies. Upon completion of the project, Franklin received a match rate of 99.526 and 99.743 percent for their address points and road centerlines respectively, surpassing the 98% requirement.
GeoDecisions continues to maintain Franklin’s data to ensure continued synchronization until the emergency services IP network (ESInet) solutions provider is ready for deployment, and will continue to work with the City on keeping their GIS data current.
