Item Information

snippet: Arizona composite geocoding service using NextGen 9-1-1 address points and road centerlines datasets. Arizona’s NG911 Composite Geocoding Service combines authoritative address points and road centerline datasets to support high-accuracy geocoding across the state. This service is designed to meet the spatial routing needs of Next Generation 9-1-1 (NG911) systems and is updated weekly using data maintained by Arizona’s local governments and the State 9-1-1 Program. The locator prioritizes the most precise match available—address points are returned first, followed by road centerlines when points are unavailable. Source data is stored in NAD83 UTM Zone 12N but can be reprojected on output as needed. This service is limited to Arizona and is not intended for use outside state boundaries. For additional information and resources, visit the AZGeo Data Hub (https://azgeo-data-hub-agic.hub.arcgis.com/).
