Case Study: Pettis County, Missouri modernizes 9-1-1 GIS data with SAM Companies

Pettis County validates 22,000 addresses with SAM Companies for NG9-1-1

Pettis County, Missouri needed to transition its outdated E-911 system to a Next Generation 9-1-1 (NG9-1-1) platform to meet a statewide mandate. This required the validation and updating of critical GIS data layers to ensure emergency calls would be routed to the correct location. The county turned to vendor SAM Companies for its GIS expertise to accomplish this critical task.

SAM implemented a thorough solution that involved sending a field crew to visually verify approximately 22,000 addresses against the existing database. Using a custom ArcGIS Collector app, the team efficiently identified discrepancies. Back in the office, SAM specialists then cleaned and formatted the road centerline and address point data to meet Missouri's strict NG9-1-1 standards. As a result, SAM provided Pettis County with accurate, new NG9-1-1 data, ensuring that first responders are now dispatched to the correct location, thereby enhancing public safety for all residents.
