NG9-1-1 GIS validation · ArcGIS Pro
Groundtruth
Validation Workbench
Check the map data behind 911. Understand the issue. Keep the reason behind the decision.

What brings you here?
Choose the starting point closest to yours. Generalist is a good place to begin for an overview.
The shared starting point
Data. A reported issue.
A decision someone can follow.
The Workbench checks geographic data through a local ArcGIS Pro toolbox. It records a reported issue, links it to the source record, and keeps the human review separate from the check’s assessment.
The data
Road records, address points, and emergency-service boundaries. A source record is one item in that data, such as a particular road segment.
The finding
A data issue or anomaly reported by a check. It points to the value or relationship that needs a person’s attention.
The review
A person records a decision and reason. Any correction happens in the authorized GIS editing workflow. A later check examines the newly supplied data.
Where it fits
Quality control at
the source of the data.
Use the Workbench to review a permitted copy of GIS data in your own environment. Local, regional, and state practitioners can connect that review to their organization’s existing maintenance and delivery process.
01 / Authoritative GIS
Maintain the source.
The authorized data steward maintains roads, addresses, and service boundaries. A reviewer may work with a permitted copy.
02 / Validation Workbench
Check. Review. Recheck.
Examine the data and document a decision. Corrections go to the authorized steward; the next check examines the next supplied copy.
03 / Existing delivery process
Submit through your program.
Continue through your aggregation, acceptance, and provisioning process. The receiving authority sets its own requirements.
The Workbench addresses local GIS validation and review. It does not operate call routing or replace receiving-system acceptance.
The work after the check
An anomaly needs context.
An analyst needs to know what to fix. A GIS manager needs to understand the decision. A 911 program needs a usable explanation when a question crosses organizational boundaries.
A decision travels forward.
The source still has an owner.
- 01 / Supplied copyExamine the data
The Workbench reads the supplied records.
- 02 / Human reviewRecord the reasoning
The finding and decision remain separate facts.
- 03 / Authorized GIS workMake any source correction
The responsible steward edits the source in GIS.
Check the next supplied copy. If the same condition returns, it starts Unreviewed with the earlier decision available as context.
Follow a real output from fictional data
One record.
The whole review loop.
Start with a state-code mismatch. Inspect the finding, record a review, and see what happens when the same value appears again.
Then try the separate exception example. Change the value or revoke the approval and watch how the queue treatment changes.
Three facts that stay separate
| Severity | Critical The check’s assessment. |
|---|---|
| Review status | Reviewed A person recorded a decision. |
| Current condition | Still present Reviewing a finding does not edit the source value. |
This distinction matters when a review is complete but a correction still needs to happen elsewhere.
Fits around your existing data
Keep working where the data lives.
Use the ArcGIS Pro toolbox with local data and confirmed field mappings. New result files hold the findings; your authoritative source remains unchanged.
Prepare
Confirm the input.
Select local layers and the applicable configuration. Inspect field mappings before using them.
Examine
Read the findings.
Inspect results across schema, attributes, spatial relationships, and supplied comparison records such as MSAG or ALI.
Continue
Take the work with you.
Use spatial results, the full JSON record, and an offline HTML report in the next stage of review.
Evaluate it against the work you own.
Start with one review cycle: the data, the decisions, the handoff, and the evidence your organization needs to judge the result.
