A point of interest (POI) is a dedicated geographic entity such as a milestone, aninstitute, anheritagesite, or a corporate office. Points of interest are the base for most of the data supporting location-based applications. The most prevalent POI categories are, for example, housing locations, eateries, fuelpumps, parking spaces, tourist attractions, etc. POIs can be both permanent like Heritage sites/monuments and temporary like shops, restaurants that are movable in nature. They are demonstrated on online maps, and are provided to users of location-based mobile applications.
