US Patent 10352718 Discovering points of entry to a location

Some embodiments provide a method for identifying one or more entrances to a point of interest or commercial entity (e.g., a shopping mall, a store, a business, etc.) using crowd sourced data received from a set of mobile devices over a specific period of time. The method identifies one or more points of entry to an enclosed area (e.g., a parking garage) associated with a point of interest (POI), as well as one or more points of entry to a building associated with the POI (e.g., a museum). When a user requests for directions to a particular POI, a navigation application of some embodiments uses these points of entry as the real driving and walking destinations when calculating and displaying a route to the particular POI.
