Abstract

A method of three-dimensional geofencing includes defining a virtual boundary in a three-dimensional geographical space, the virtual boundary including lateral position parameters and an altitude parameter. A boundary-related event and an action to be triggered based on the position of a trackable object is defined with respect to the virtual boundary. The position of the trackable object is estimated based on lateral position values and an altitude value associated with the trackable object. The action is performed if it is determined that the position of the trackable object triggers the boundary-related event.
