Reference frame for heights LHN95 (National vertical network 1995, orthometric heights)

National vertical network 1995 (in the renewed Swiss reference system for height LHN95): The potential-theoretically rigorous height reference frame of the new national survey LV95 is based on precise levelling data (from 1902 until today), the orthometric heights from the geoid model CHGeo2004. The height reference is the orthometric height of the fundamental point in Zimmerwald. LHN95 will not be used in cadastral surveying in the near future. The exact height transformation CHTRF2004 <-> LHN95 is guaranteed.
