Public Safety Answering Point (PSAP) boundaries for use in NG911 call routing and answering.
Update Frequency
This dataset is updated monthly
About [link]
The Next Generation (NG) 9-1-1 GIS Data product is a comprehensive dataset that contains various geospatial data layers benefiting public safety agencies within state and local government. The core layers in this product are street centerlines, address points, and Public Safety Answering Point (PSAP) boundaries which form the backbone of the Next Generation 9-1-1 Call Routing System.
This dataset facilitates Tennessee’s participation in the National Address Database and is also used to support many other mapping and geocoding requirements at the state and federal level.
