Ferry Link
A Ferry Link is a linear spatial object which represents the connectivity of a vehicular ferry route across a body of water. A Ferry Link will only be captured where both terminals are located within Great Britain and where there is a timetabled service which is available to the public. Ferry routes with a terminal located outside of Great Britain are not captured (for example, Dover to Calais) and neither are ferry routes where the service is not available to the public.
