The layer contains the zoom-dependent mileage lines with the information on the operating kilometers of the motorway. In addition to stationing, there is also a system of (operational) mileage on the motorways. The federal highways are provided with continuous length information in kilometers from their physical beginning to their end, regardless of administrative boundaries. The mileage (usually the stationary operational mileage) is to be understood as a clear reference for stationing (measured to the nearest 1 m). Lengths or length intervals in stationing and operational mileage are identical.
