Levelling bencmarks are points for which the elevation is determined by means of precision levelling. The Levelling bencmarks are very well defined in terms of elevation by means of precision levelling, but in many cases the ground plane coordinates are very imprecise. Many Levelling bencmarks close to roads have unfortunately been lost.
