Abstract
Natural navigational guidance, provides enhanced guidance instructions that take advantage of unique geographic features along a navigated route to specify maneuver points. Guidance points are clearly visible, unambiguous, and locally unique features in the geography of the maneuver area that can be used to aid the user in discovering the place where the maneuver point is. Within a guidance point selection area, a specific guidance point type has a more strict area within which it can be used. A natural guidance point selection area for an upcoming maneuver to be navigated is determined, and a unique geographic feature within the determined natural guidance point selection area is selected as a natural guidance point for navigation of the upcoming maneuver. A turn-type natural guidance point for an upcoming maneuver to be navigated is generated when the user device is within the natural guidance point selection area.
