NENA Standard for NG 911 GIS Data Model

AdamLodge — Thu, 17 Aug 2017 17:41:47 GMT

Has anyone created a file geodatabase or xml schema document that, to the extent possible, implements the full data model defined in NENA NG911 for GIS standard?

https://dev.nena.org/higherlogic/ws/public/download/9828/20161206_NG9-1-1%20GIS%20Data%20Model_PubRvw.pdf

If so, I (and perhaps others) would find it hugely helpful to get access to that in order to save the time it will take to define the feature classes.

Many thanks,

Adam

I'm also curious if someone has developed this (though I don't have an immediate need). A year ago when we had a related thread on NextGen 911 it seemed like there was not alot of action by anyone to implement it yet. Maybe that has changed?

Next Generation 911 (NextGen) rollout?

I know that City of Yuma, Arizona has created a full file geodatabase data model. I do not know that the city is willing to share it to outside users yet since the NENA GIS data model standards has not yet be finalized but reach out to the GIS administrator within the information technology department.

NENA published the data model last month, 6/16/2018.

NENA-STA-006.1-2018

https://www.nena.org/resource/resmgr/standards/nena-sta-006_ng9-1-1_gis_dat.pdf

I've read this thread before, and revisited today because it's time to create the schema. I found an empty FGDB schema at Montana's website: ftp://ftp.geoinfo.msl.mt.gov/Data/NonSpatial/NG911/NENA_NG911_GIS_Data_Model.zip

Montana's schema is a start, it contains the "required" layers, but not all the "strongly recommended" and "recommended" layers. The spatial reference needs to be reset to WGS84 (EPSG4326) on the first layer I checked. No other coordinate system is acceptable.

That looks like NENA published a pdf document, not an actual model. Having left the 9-1-1 industry for greener pastures, it still amazes me how much buzz there is about NG 911 but so little actual implementation, not to mention standardization.

Our office here at Lake County, Illinois took a look at Montana's empty FGDB and found numerous discrepancies compared to the June 16, 2018 published specs by NENA. Three of us have painstakingly proofed and made corrections, including the projection which was in the southern hemisphere for some reason. We have also added all of the optional tables and fully created all of the possible domains. Attached below is an Esri XML Workspace Document. Note that some domains such as County, PostalCode, and PostalCommunityName are empty, we will leave those up to you to fill in for your locality. Also note that the specs do not provide names for domains and many domains are shared among several fields. Where possible a generic domain name was used following the Montana lead to allow sharing among the fields. If you find any errors or omissions, please reply to this post.

Enjoy!

Kansas has this:

Kansas Data Access and Support Center - Next Generation 911 (NG911)

under standards, tools, and policies, we have data model templates for the two state plane (projection) zones. We are at version 2.1 and have incorporated legacy MSAG as geoMSAG. We just add "geo" to acronyms like MSAG and that makes it all better.

JonHall — Tue, 02 Oct 2018 15:49:41 GMT

Kansas is doing great things! However, the NENA standard is WGS84, not state plane.

Best regards

Thanks! I had started this effort on my own, but hadn't finished.

Thanks Jon. We just wanted to get something out there that matched the NENA standard. Entities will no doubt change it up for their own use. Kudos to Kansas and everyone else who started working on this several years ago! It would be interesting to hear about any issues the early adopters have run into.

It makes sense that the NENA standard is WGS84 and WGS84 is used on the back end. However it does not make sense for data stewards to define and work with geodatabase feature data in WGS84 coordinates.

No it doesn’t! Which is why I am right now creating an Illinois stateplane version – in several flavors – for distribution to our regional partners!

All - thanks for pointing out some of the issues with the Montana version of the data model. I'll go back and get it fixed up, or maybe just take the Lake County XML Workspace Document and incorporate it. Either way, I don't want something with issues out there causing people problems.

I do not see any COGO, GPS or Editor Tracking attributes in their GIS standard.

Thank you Peter! This is a great start as we begin to plant for our MAJOR schema update!!!

Kasey, Peter, all- FYI

Last month, NENA's Data Structures Committee spun-off a GIS-data-model-template workgroup to publish a Python script that creates a new File GDB with the schema specified in NENA-STA-006.1

After looking at contributions by Michael Fashoway , Lake County, and others, the workgroup chose to build upon a Python script developed in the state of Washington (my apologies for not recalling the GIS folks who deserve credit! they will be acknowledged by NENA in the published info doc).

The work group may post the Python script for public comment in a few weeks or months, maybe before the June 2019 NENA conference in Orlando. Michael and I are members of that workgroup, and someone will ping this thread or the "911GIS" group when the Python script becomes available.

Surprisingly, after ten years of work, the layer names are not explicitly specified by STA-006.1, and some field names are ambiguous, open to interpretation, or inconsistent with naming conventions used in the document. The issues being resolved by the data model template workgroup are being shared with the GIS data model workgroup, who will include those considerations in "version 2"of STA-006.

Kasey, Peter, all- FYI

An update on NENA's Data Structures GIS-data-model-template workgroup:

I misunderstood the WG deliverable, the intent is not to publish the Python script, but to publish an empty File GDB with the schema specified in NENA-STA-006.1

CREDIT for the original Python script belongs to Jason Guthrie at TComm911 in Olympia, WA.

The FGDB generated by the Python script is maturing, but it looks like another month or so before NENA publishes a final draft for public review & comments.

GIS Data Templates Available for Public Review

Aug 27, 2019 3:38 PM

NENA's GIS Template Working Group is pleased to announce the availability of its DRAFT GIS data templates for public review and consideration. The GIS templates are a direct interpretation of the NG9-1-1 GIS Data Model (NENA-STA-006.1-2018).

The primary purpose of the GIS data templates is as a common data structure for data exchange between agencies or their vendors. As best stated by NENA-STA-006.1-2018, "It is not expected that every entity will use the GIS data model described within this standard (NENA-STA-006.1-2018) for its day-to-day internal use and maintenance but it is expected that each entity will be capable of exporting their internal GIS data model into a given GIS file format that complies with this standard as frequently as may be necessary." It is the goal of the GIS Data Template Working Group to provide a GIS Template for entities to use in order to fully, and consistently, meet this requirement.

Before the GIS Template Working Group publishes its final deliverables, it is interested in hearing from any agency willing to extract, transform, or load (ETL) their GIS data into one of these templates. The working group is particularly interested in hearing about any complications, challenges, limitations or other problems associated with the ETL process.

There are 4 files provided as part of this public review period and are combined into the zip file located here.

First, two scripts the GIS Template Working Group used to create the GIS data templates are being provided (i.e. .sql & .py). While the scripts are not, technically speaking, the official deliverables of the working group, the working group felt it was important to be open about how the GIS template deliverables were created.

Second, two GIS data template structures are being provided. One data template structure is provided as a Esri File Geodatabase which the user will need to first extract. The other data template structure is provided as a PostgreSQL database dump file.

The GIS Template Working Group would appreciate your review by Friday the 13th of September. Should you have any questions, please contact Jason Horning.

Is the NENA NG 911 GIS standard directly consumable for major consumer products such as Esri StreetMap Premium, Here Maps, Apple Maps, Google Maps, Waze Maps, etc.?
