Policy, location, routing, and response quality connected in one operational model.
PSAP Technology
GIS for Emergency Routing
Geographic Information System
In NG112, GIS is operational infrastructure. Boundaries, address points, road centerlines, building data and jurisdiction layers may influence routing and responder guidance. Bad GIS data can cause wrong-PSAP routing even when protocols work perfectly.
What it does
GIS supports service boundaries, map display and location interpretation for emergency routing and PSAP operations.
GIS provides the geographic truth used by routing functions and PSAP display tools.
How it works
- Maintains service boundaries and location layers.
- Feeds ECRF/LVF-like routing and validation functions.
- Displays caller location and operational context inside the PSAP.
Key interfaces and protocols
- ECRF/LoST data inputs
- LVF validation
- PSAP mapping
- CAD map layers
Systems it interacts with
- ECRF
- LVF
- PSAP
- CAD
- Location
Common failure modes
- Boundary updates lag real operations.
- Address points do not match civic records.
- Floor/indoor data missing for large venues.
- Projection or coordinate assumptions differ.
Implementation considerations
- Version and audit GIS changes.
- Test edge points and known trouble addresses.
- Treat GIS stewardship as an emergency service role.
Standards
- IETF LoST concepts
- ETSI NG112 references
