NG911 Data Prep and AGRC’s Address Cross Check Project

Project Background

As the State of Utah moves closer to Next-Generation-911 (NG911) implementation, data prep and data clean up are the next, most logical steps for GIS readiness.

Please visit Utah's NG911 GIS Roadmap for more information on how this project fits into the larger picture. Specific to this project, the section titled Address Component Cross Check will give you a good background on why we are doing this.

Please contact Greg Bunce at AGRC to have your jurisdiction processed. In return you will receive a discrepancy report (FileGeodatabase and ArcMap document) indicating records that need further inspection.

The Address Cross Check Project

AGRC’s Address Cross Check project is guided by NG911 GIS standards established by National Emergency Number Association (NENA). To assist in complying with these standards, AGRC has created a custom process to perform validation checks on the Site/Structure Address Points and Road Centerline datasets.

The process cross-checks the address components from Site/Structure Address Points and Road Centerlines - checking for attribute, distance, and address range issues (mismatches). The project outputs a file geodatabase containing the address points and road centerlines containing possible issues, as well the input, source data for map reference. An overview of the code operations are as follows:
