National height network LHN95

In the course of national survey LV95, the need for a corresponding vertical reference frame arose. LHN95 is a potential-theoretic, rigorous height system which takes kinematic phenomena (uplift of the Alps) into account and is based on rigorous orthometric heights. The origin for LHN95 is the fundamental point of national survey LV95 in Zimmerwald.
