US Classification:

701211, 701 25, 701201, 701208, 701209, 34235713

Abstract:

A method for operating a navigation system is disclosed. An ordered plurality of interconnected segments providing a route from an origin to a destination is obtained. A guidance message for each of the segments is formed. The step of forming the guidance message comprises determining whether to reference a previous segment and adding a reference to a current segment.

US Classification:

701211, 701 25, 701201, 701208, 701209

Abstract:

A method for collecting geographic data for use with a navigation system identifies a pedestrian segment associated with a path. A text description of the pedestrian segment is collected. The text description includes one of a predetermined number of phrases and name of at least one feature visible from a location of the pedestrian segment. Data representing the pedestrian segment is stored in the geographic database.

International Classification:

G01C 21/30

US Classification:

701211, 701 25, 701208, 701209

Abstract:

A method for collecting geographic data identifies a pedestrian segment associated with a path. Location information for the pedestrian segment is collected. Additionally, lighting level attribute information is collected for the pedestrian segment. The location information and the lighting level attribute information are stored in the geographic database that is stored on a computer readable storage medium.

International Classification:

G01C 21/30

US Classification:

701211, 701 25, 701208, 701209

Abstract:

A method for operating a navigation system computes a pedestrian route for travel by a pedestrian. A request to calculate the pedestrian route from an origin to a destination and a walking preference for the pedestrian route identifying a feature of the pedestrian route are obtained. A geographic database associated with the navigation system is accessed for data representing at least one pedestrian path. The data representing the pedestrian path includes lighting level attribute information for the pedestrian path. A valid solution pedestrian route from the origin to the destination comprising a series of connected pedestrian paths that support the walking preference is determined.

US Classification:

701428, 701409, 701410, 701433, 701434

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.
