Method of collecting information for a geographic database for use with a navigation system
First Claim
1. A method of operating a navigation system comprising:
- receiving a request for a pedestrian route between a first location on a road network and a second location inside a building off of the road network;
accessing a geographic database stored on a computer readable medium associated with the navigation system to obtain data representing a plurality of road segments including data representing a sidewalk along the road segment and data representing a crosswalk associated with the road segment;
accessing the geographic database to obtain data representing a plurality of pedestrian segments located inside the building, wherein the pedestrian segments are paths for travel by a pedestrian inside the building;
accessing the geographic database to obtain data representing at least one orientation node providing a connection between one of the road segments and one of said pedestrian segments; and
determining a solution route comprising a series of connected road segments and a series of connected pedestrian segments between the first location and the second location, wherein said solution route passes through at least one orientation node and the road segments that have associated sidewalk and crosswalk.

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.
