A geofence is a geographic boundary that you can define and associate with your devices. HERE Tracking can then notify you when a device transitions into or out of a geofence.

Geofences can be circular or polygonal. Circular geofences are defined by a centre geo-coordinate and a radius while polygonal geofences are defined as a set of geo-coordinates.

Indoor geofences can be created by defining the floor properties in the geofence definition.

Once created, a geofence can be associated with a device. This association means that every time a location update is received from the device, it will be compared to the area of geofence. If the device has transitioned from outside the geofence to inside or vice versa, a transition event is recorded and HERE Tracking will generate a notification. For indoor geofences a transition is recorded only if the position of the device is indoors, and the floor ID and level of the position match the geofence floor definition.
