Overview#
The Geofencing domain provides geographic boundary management for emergency alerts, incident response, and location-based notifications. It supports multiple geofence types, device tracking, KML import/export, population estimation, auto-expanding boundaries, and real-time geofence matching when devices enter or exit defined areas.
Key Features#
- Multiple geofence types (evacuation, shelter-in-place, search area, restricted, alert zone, critical zone, surveillance, hazard, custom)
- Geofence lifecycle management (active, pending, expired, cancelled, draft)
- GeoJSON polygon/multipolygon support with spatial indexing for fast queries
- Auto-expansion over time with configurable rate and maximum limits for modeling spreading hazards
- Device location recording with automatic entry/exit/dwell detection and notification triggers
- KML import/export for bulk boundary management and external sharing
- Population estimation and address counting within boundaries
- Version history tracking for all boundary changes
- Buffer zone generation from existing geofences
- Geofence overlap analysis with percentage calculations
Use Cases#
- Creating and managing evacuation zones during natural disasters with auto-expanding boundaries
- Recording device locations to detect when personnel enter or exit active geofence zones
- Importing search area grids from KML for search-and-rescue operations
- Estimating affected population within geofence boundaries for resource planning
Integration#
The Geofencing domain integrates with Alert Campaign for notification targeting, Incident for emergency response, Location for POLE profiles, DOC Location for duty-of-care tracking, and Map for visualization.
