Abstract: Representation of linear features in a location content management system is disclosed. A linear feature is represented using a sequence of routing points that define a unique path when routed on a map through those points. A routing point consists of latitude, longitude, and optional stack position. Stack position defines an upper or lower level of a double-decker bridge or road. The data representing the linear feature is stored outside of a geographic database.

Abstract: A navigation system includes a navigation-related information server and one or more customer-interface servers. Each customer-interface server receives requests for navigation-related information from end users who have end user computing platforms. The end users send their requests for navigation-related information from end user computing platforms over a data network to the customer-interface servers. In order to respond to the end users, the customer-interface servers request language and format-independent navigation-related information from the navigation-related information server. The navigation-related information server receives the requests from the customer-interface servers. To response to each request for navigation-related information, the navigation-related information server uses one or more geographic databases to formulate language- and format-independent data structures. These language- and format-independent data structures are sent to the customer-interface servers.
