NAVIGATION BY POINTS OF INTEREST

A point of interest, or POI, is a specific point location that someone may find useful or interesting.

A GPS point of interest specifies, at minimum, the latitude and longitude of the POI, assuming a certain map datum. A name or description for the POI is usually included, and other information such as altitude or a telephone number may also be attached. GPS applications typically use icons to represent different categories of POI on a map graphically.
