Data layers
How to push custom operational overlays — hydrants, ANPR cameras, asset locations — into the responder app.
Supported sources
Section titled “Supported sources”- ArcGIS Online / Server — direct feature-layer subscription
- CSV / GeoJSON — uploaded via the admin portal or pushed via API
- PostGIS — replication endpoint configurable per layer
Layer types
Section titled “Layer types”- Point — hydrants, ANPR cameras, vulnerable-person locations
- Polygon — risk zones, training areas, secure sites
- Line — pipelines, restricted routes, no-go corridors
Per-role visibility
Section titled “Per-role visibility”Layers can be tagged with one or more roles. A layer tagged fire will be visible to fire crews; a layer tagged fire, police will be visible to both.
Update cadence
Section titled “Update cadence”- Real-time layers (e.g. live ANPR alerts) — pushed via WebSocket, surface in < 2 seconds
- Daily layers (e.g. hydrant maintenance state) — synced via cron job, cached on the cab
- Static layers (e.g. service area polygons) — bundled with the cab cache for offline use
