Arizona Geospatial Validation and Aggregation

The Arizona 9-1-1 Program is working to improve the accuracy and reliability of the geospatial data used in the state's NG9-1-1 system to support the 81 Public Safety Answering Points (PSAPs) with geospatial routing. To do this, the program has implemented a workflow using 1Spatial to validate and aggregate various types of data, including address points, road centerlines, emergency service boundaries, and legacy datasets such as the Automatic Location Information (ALI) and Master Street Address Guide (MSAG). This workflow is known as the geospatial data supply chain, and it helps to ensure that the data used in the 9-1-1 system is accurate, up-to-date, and consistent.

The geospatial data supply chain also supports the requirements of the Next Generation 9-1-1 (NG9-1-1) system and the Arizona Department of Transportation (ADOT), including the use of the Linear Reference System (LRS) and the state spatial data infrastructure (SDI) known as AZGeo. The data supply chain is also helping to support the Federal Communications Commission (FCC) Broadband Challenge Process, which aims to improve the availability and reliability of broadband service in rural and underserved areas.

Overall, the Arizona 9-1-1 program is working to improve the quality and consistency of the geospatial data used in the state's 9-1-1 system to enhance the efficiency and effectiveness of the system and better serve the community's needs.
