NENA NG9-1-1 GIS Data Model Available for Public Review

By Cheryl Benjamin  |  Jan. 9, 2017

The National Emergency Number Association (NENA) recently released the NENA Standard for Next Generation 9-1-1 (NG9-1-1) GIS Data Model for public review.  Under development for over 6 years, the NG9-1-1 GIS Data Model is designed to support civic location address data management in a NG9-1-1 System. NENA was a major participant in the development of the FGDC’s United States Thoroughfare, Landmark, and Postal Address Data Standard and closely aligned the NG9-1-1 Data Model to the FGDC Standard, but it does have some differences.

The public is invited to review the document and submit comments following the instructions below (direct link Comments will be accepted until February 28.

A NSGIC 30-minute webinar about the standard was recently held and is now available on NSGIC’s NG9-1-1 library page ( Those interested in commenting on the document are strongly urged to first review the webinar as it explains what the NG9-1-1 GIS Data Model Standard is, how the document is structured, the GIS data layers needed in a NG9-1-1 system, their structure and use in required NG9-1-1 functional elements, items deferred for future work, how to participate in the public review, and the document’s relationship to other NENA GIS-related standards.

Based on my experience and understanding of the NENA document development and review process, for your comments to be understood and considered, you should:

  • Clearly articulate your concern
  • Provide supporting references, examples, and justification
  • Include suggested text with your proposal
  • Offer to be on workgroup calls for a complicated comment
  • Consider noting new items as future development work

All submitted comments are available for public review at the bottom of the document’s web page. If there is a comment that you strongly agree with, show your support by submitting it again!  An issue submitted by multiple people across the US, shows that the concern is not just limited to one person or one region, but is a national concern and need to be addressed.

The document is lengthy (86 pages) and February 28 is not really that far away so time to get reading!! 

NENA Standard for NG9-1-1 GIS Data Model available for Public Review and Comment

NENA Standard for NG9‑1‑1 GIS Data Model, NENA-STA-006.1-201X (DRAFT) is available for Public Review and Comment. This standard defines the Geographic Information Systems (GIS) Data Model, which supports the NENA Next Generation 9‑1‑1 (NG9‑1‑1) systems of location validation and both geospatial call or dispatch routing. This is the standard to be referenced by GIS practitioners. This model also defines several GIS data layers (layers) used in local Public Safety Answering Point (PSAP) and response agency mapping applications for handling and responding to 9‑1‑1 calls.
