Fixed points

Fixed points of the national survey

A fixed point is a point permanently secured with a stone or a bolt (sometimes under a shaft) with known coordinates and/or known height. The fixed points form the basis of all data with a spatial reference.

Land levelling (height reference system)

The Liechtenstein national level is attached to the Swiss national level of 1903 and refers to a height mark in a rock in the harbor basin of Geneva, the Pierre du Niton, with a height of 373.60 m above mean sea level in the port of Marseille. Derived from this reference point, various levellitically determined contour lines were measured, the fixed points of which form the reference network for the service heights valid in Liechteinstein
