Abstract: There is provided a method and system for automatically generating navigation route data for a vehicle. The method and system provide for storing in computer readable form at least one path object having a predetermined path object type which corresponds to a distinct predefined path type; and, for selectively reading and executing at least one such path object to generate a composite navigation route for guiding the given vehicle's travel. The composite navigation route may be formed by one or more path components defined by the path object. Each path object includes a plurality of defining parameters for geometrically configuring each path object's corresponding path type to form at least one specific path component. Each path object also includes a predetermined set of instructions for geometrically rendering its path component in accordance with the defining parameters.
