What is the NG9-1-1 GIS Validator?


The Validator is a free online service that compares and scores your data to the NENA Standard for NG9-1-1 GIS Data Model.  It is your first step towards ensuring your data meets the NG9-1-1 GIS data standards.  The GIS layers that the Validator currently checks are:

  • Road Centrelines
  • Site/Structure Address Points
  • Emergency Service Boundaries
    • EMS Polygons
    • Police Polygons
    • Fire Polygons
  • Provisioning Boundaries

Simply upload your existing geodatabase or shapefile to receive a downloadable summary and detailed list of discrepancies within minutes. No software installation is required.

The Validator performs more than 600 tests to confirm your data meets the high standards for public safety data. In this video, we go over the validation process and the reports that are generated.

What does it do?


NG9-1-1 is dependent on GIS data. Data must be from authoritative sources and meet the new NENA standards.

The Validator checks that you have the mandatory attributes for each layer you are testing, checks your field names, tests the domain values, and ensures that each attribute meets the data type and length requirement.

You can re-upload and check your data as many times as needed until it matches the NENA model.

FAQs

It is based on the NG9-1-1 GIS Data Model published by NENA: https://www.nena.org/page/NG911GISDataModel

This is correct. It is not mandatory that any data change be reflected in the 9-1-1 ecosystem within 72 hours. This is an aspirational goal.

Yes, there is an extensive list of suffixes that are valid. If you have one that is not on the list, please email Robert Harris, Co-Chair of ESWG TIF-92, (rharris@esri.ca), and we will work with NENA to add it to the list.

Yes. The NENA GIS Data Model for NG9-1-1 will accommodate requirements for both the US and Canada.

No, there is no limit.

No, there is no registry. Users design the string according to the NENA data model spec.

It is not available for download at this time, but the Validator has a section (tab) that details the specifications. The NENA Data Model schema should be available sometime in Q3.

Yes. Vertical addresses must be individual site address points.

The Provisioning Boundary defines the 9-1-1 Authority’s area of GIS data provisioning responsibility. Boundary information must be agreed to by all adjoining provisioning providers and cannot contain unintentional gaps or overlaps. This effectively becomes a geofence for the 9-1-1 Authority for data submitted through the Spatial Interface and determines the entity responsible for discrepancy resolutions.

The ESB is the area which defines the agencies (police, fire, ambulance) responsible for providing service to a location.

No, it does not. However, we are currently working on solutions to perform these checks.

Yes, they can. 

It must be a zipped file containing shapefiles or a geodatabase (GDB).

Yes, and each unit must be an individual site address point.

No, the Validator does not retain any copies of data submitted.

No, it is a web application.

The authoritative data providers, working with their neighbouring jurisdictions.

The NENA NG9-1-1 GIS Data Model will accommodate requirements for both the US and Canada. Work is currently underway at NENA to create this single model.  

This is a choice for the municipality to make in consultation with their emergency service providers.
