NG911 GIS Data Validation Metrics

The NG911 GIS Conformance Dashboard is designed to ensure that geospatial data that supports call routing is as accurate and efficient as possible. Here's how it works:

  1. Data Sources: The dashboard uses several key data sources:

    • Location Database: Contains wireline subscriber information.
    • Master Street Address Guide (MSAG): A comprehensive list of street addresses and associated information.
    • Site Structure Address Points: Precise locations of structures like houses or buildings.
    • Road Centerlines: Detailed data on roadways.
  2. Data Matching: The core function of the dashboard is to match and compare these data sets. It checks how well the Location Database and MSAG information aligns with the Site Structure Address Points and Road Centerlines. This process is known as a "match rate."
  3. Integration with 1DataGateway: The State of Arizona uses 1DataGateway to validate and aggregate information according to the NENA NG911 GIS Standard. This standard ensures that all geographic data is accurate and uniform, which is crucial for emergency response.

  4. Weekly Updates: The dashboard is updated weekly, ensuring the data it contains is current and reliable.

Purpose and Importance:

  • The primary goal of this dashboard is to enhance the effectiveness of the Next Generation 9-1-1 system.
  • 911 calls are routed more quickly and precisely by ensuring high address and location data accuracy.
  • This tool is critical in public safety, directly impacting the Public Safety Answering Point (PSAP) operations.

In summary, the NG911 GIS Conformance Dashboard is a vital tool for maintaining the integrity and reliability of geospatial call routing by regularly checking and integrating geographic data sources.
