GIS Data Model, Part 1
Background

Background – What is the Data Model?
https://www.nena.org/page/NG911GISDataModel
3.
Background – Why is it needed?
• Presence Information Data Format-Location Object (PIDF –LO)
o Civic Location Data Exchange Format (CLDXF)
• Consistency
• Interoperability
• Backwards compatibility

ECRF: Emergency Call Routing Function
• Provides information about responder agencies and routes the initial 9-1-1 call to correct PSAP
5
LVF: LOCATION VALIDATION FUNCTION
• Validates civic locationsPSAP “A”
(X,Y)

The Basics - Metadata
• Identification
• Contact
• Quality
• Spatial Reference
• Lineage
• Legal
• Temporal
• Metadata Reference
• Metadata Standard (FCGC)
6© 2019 Comtech Telecommunications Corp.© 2019 Comtech Telecommunications Corp..
The Basics - NGUID
• NENA Globally Unique IDs (NGUID)o Local ID + Agency Identifier
o Example:
Local Road ID = RCL120853
Agency Identifier = county.wa.us
7© 2019 Comtech Telecommunications Corp.© 2019 Comtech Telecommunications Corp..
The Basics – Spatial Reference
• Maintenance = Local
• ECRF/LVF purposes = WGS84
• NSDI Standard = 1:5000o +/- 13.89 feet at 95% confidence

The Basics – Horizontal Accuracy

GIS Data Model - Layers
• Requiredo Road Centerlines
o Site/Structure Address Points
o Provisioning Boundary
o Emergency Service Boundary (PSAP, EMS, Fire, Law)
• Strongly Recommended
• Recommending

GIS Data Model – Attribute Conditions
Examples:
• Mandatory NGUIDo MUST Populate
• Conditional ESN Lefto Does it exist?
▪ Yes = MUST Populate
▪ No = Leave Blank
• Optional Service Numbero Up to You

Provisioning Boundary
© 2019 Comtech Telecommunications Corp. 11© 2019 Comtech Telecommunications Corp..
Provisioning Boundary
Area of GIS data provisioning responsibility, with no unintentional gaps or overlaps
• Stakeholders MUST Agree
• Used by ECRF
• Excludes Features Outside Boundary

Emergency Service Boundaries
Defines the geographic area for the primary providers of response services
• Stakeholders Must Agree
• Determines who is responsible for providing service to a location
• Direct an Emergency Incident Data Document
• Used by ECRF
