Abstract
A method for operating a navigation system computes a pedestrian route for travel by a pedestrian. A request for the pedestrian route between a first location inside a building and a second location inside the building is obtained. A geographic database associated with the navigation system is accessed for data representing a plurality of pedestrian paths. A solution pedestrian route from the origin to the destination comprising a series of connected pedestrian paths between the first location and the second location is determined. A guidance message that identifies a feature visible from at least one of the pedestrian paths is provided.
