Maximizing NG911 Data Integrity with ArcGIS Pro Attribute Rules
Having clean NG9-1-1 data is crucial to emergency response entities because it ensures they receive accurate locational information which can lead to faster response times and in turn can save lives. In the world of GIS, attribute rules within ArcGIS Pro play a significant role in upholding this data integrity, particularly when applied to NG9-1-1 datasets. Ensuring accuracy, consistency, and efficiency, attribute rules streamline data maintenance processes and enhance reliability.
Automating Data Maintenance
Attribute rules can be used to maintain address point and street centerline data within large NG9-1-1 datasets. By leveraging calculation rules, users can automate the population of legacy street fields from full street name fields and vice versa. Additionally, attributes such as longitude, latitude, NGUID, and concatenated full street name fields can be populated automatically, minimizing manual intervention and reducing the risk of errors.
Changing the Street Name Pre Direction automatically updates the Legacy Pre Direction, and Full Street Name fields. Calculation rules can make editing workflows more efficient.
Enforcing Data Constraints
To ensure data accuracy, constraint rules play a crucial role in preventing accidental and/or inaccurate information when entering data. By enforcing constraints such as adherence to the Master Street Name Table for road centerline street names, attribute rules ensure data consistency and reliability, minimizing the risk of data discrepancies.
Leveraging Esri Resources
Esri provides a wealth of resources that allows users to access the full potential of attribute rules. I personally utilize the desktop application template from the “Address Data Management” Solution in ArcGIS Online. To me, this stands out as a great starting point for configuring attribute rules tailored to NG911 data management requirements. By deploying this solution in ArcGIS Online and utilizing the desktop application template, users have access to preconfigured rules designed to optimize NG911 data workflows.
Enhancing Validation Capabilities
The desktop application template includes validation rules that facilitate quality control of NG9-1-1 address point and street centerline data, pinpointing areas requiring attention. Notably, these validation rules can now be applied within a file geodatabase, expanding their utility beyond the previous enterprise-only environment. By configuring validation rules and integrating error layers, users can efficiently identify and address common trouble areas during NG9-1-1 data cleanup.

Focus on Standards and Best Practices
When conducting NG9-1-1 data cleanup, it's essential to prioritize common trouble areas outlined by NG911 standards and best practices. These may include road centerline overlaps, duplicate address points, parity issues, and discrepancies between addresses and street names. By aligning with NG911 standards specific to each state, users can ensure data accuracy and compliance with regulatory requirements.
In conclusion, utilizing attribute rules within ArcGIS Pro enhances NG9-1-1 data integrity. By automating data maintenance tasks, enforcing data constraints, and using validation rules for quality control, you can streamline workflows, minimize errors, and contribute to the reliability of emergency response systems.
