Two geofences defined in a GPS application. A geofence is a virtual "perimeter" or "fence" around a given geographic feature. [1] A geofence can be dynamically generated (as in a radius around a point location) or match a predefined set of boundaries (such as school zones or neighborhood boundaries).
