A Geofence is a virtual perimeter around a geographic area using Location-Based Services so that when a GPS-enabled device enters and/or exits the area a notification is generated.

This notification contains driver and/or vehicle identification and location data which can be sent to a mobile device or an e-mail account as well as recorded for reporting purposes.

A Geofence can be set for all employees, groups or individual employees. Fences can be either permanent or temporary. There are two kinds of Geofences: polygonal and radial. Examples of both can be seen in the screenshot at the right.

So what are some of the uses and benefits of Geofencing?

  • Location-based messaging can be used with radial fencing to send emergency-related alerts.
  • A Geofence can be set in a radius around a customer’s site so that an e-mail alert can be automatically sent to the customer advising of the imminent arrival of your driver.
  • By capturing both the arrival and departure times, a business can automatically capture the duration of a stop.
  • A business can be automatically alerted when either an individual employee or any employees enters an unauthorized location.
