Point of interest, or POI, is a specific point location that someone may find useful or interesting. The term is widely used in GPS navigation software. In this area the location of this point is called a waypoint.
A GPS point of interest consists at the very minimum of the latitude and longitude of the POI, although a name or description for the POI is usually included too. GPS applications typically use icons to represent different categories of POI on a map graphically.
