NG911 GIS Data Validation Metrics
The NG911 GIS Conformance Dashboard is designed to ensure emergency call systems are as accurate and efficient as possible. Here's how it works:
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.
- 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."
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.
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.
- Emergency services can respond more quickly and precisely by ensuring high accuracy in address and location data.
- This tool plays a critical role in public safety, as it directly impacts the efficiency of emergency response teams.
In summary, the NG911 GIS Conformance Dashboard is a vital tool for maintaining the integrity and reliability of emergency response systems by regularly checking and integrating critical geographic data sources.
