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 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, wherein the pedestrian segments are paths for travel by a pedestrian off of the road network;
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 road segments that have associated sidewalk and crosswalk.

Abstract
A method of operating a navigation system is disclosed. A request for a route between a first location on a road network and a second location off of the road network is received. A geographic database stored on a computer readable medium associated with the navigation system is accessed 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. The geographic database is accessed to obtain data representing a plurality of pedestrian segments and data representing at least one orientation node providing a connection between one of the road segments and one of said pedestrian segments. 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 is determined.

8. A method of operating a navigation system comprising:
-
receiving a request for a pedestrian route between an origin and a destination; receiving a walking preference for said pedestrian route; accessing a geographic database stored on a computer readable medium associated with the navigation system to obtain data representing a plurality of candidate segments for the pedestrian route; evaluating attribute information for each of the candidate segments for conformity with said walking preference, wherein said attribute information includes at least one feature selected from the group consisting of;
type of transportation allowed, wheel chair accessible, pets allowed, lighting level, noise level, pollution level, activity level, tree lined and weather effects; anddetermining a solution route comprising a series of connected segments between the origin and the destination, wherein said solution route matches said walking preference. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
