System of Land Survey LV95 — Liechtenstein
Description
New, locally stored reference system of the Swiss National Survey LV95, which will be introduced in the future as the basis for the official survey. CH1903+ uses the same ellipsoid dimensions (Bessel 1841) as CH1903. The spatial coordinate axes X,Y,Z are derived directly from CHTRS95 by 3 translations. The map projection system (Swiss Grid) is identical to CH1903. The starting point for the heights is the new fundamental point Z0 of the Zimmerwald geostation, whose orthometric value H0 = 897.9063 was chosen in such a way that the height of the “Repère Pierre du Niton” in the port of Geneva nears the orthometric height 373.6 m.
The reference framework was adopted by Liechtenstein without modification.
