Abstract

The preferred embodiments of the present invention are directed to an improved mapping and navigational system. Specifically, the present invention is directed to a system for defining and assigning geographical boundaries to points of interests on a graphical map, where the geographical boundaries preferably correlate to spatially defined boundaries of the respective points of interests. In accordance with one embodiment of the present invention, the points of interest, along with the respective defined geographical boundaries, can be transferred from a personal computing device to a telecommunication device, such as a portable communication device, so as to be used for mapping purposes and to set off proximity alerts when the portable communication device, equipped with a GPS unit, enters or exits the geographical boundary of a particular point of interest.

Claims

1. A machine-readable medium containing a set of executable instructions for causing a computer to perform a method for identifying a point of interest on an electronically generated graphical map, said method comprising the steps of:

generating an electronic graphical map;

designating a point of interest on said electronic graphical map;

defining a geofence for said point of interest, said geofence being a boundary surrounding the center of the point of interest; and

displaying said geofence on said electronic graphical map.
