Reference system CH1903

The old, still official reference system for cadastral surveying which was defined and introduced in 1903. The system comprises the definition of a reference ellipsoid (Bessel 1841) fixed in position and orientation to the old fundamental point (old observatory in Bern), the transformation in CHTRS95 and the Swiss oblique conformal cylinder projection ("Swiss Grid"). CH1903 also defines the old official height system for which the "Repère Pierre du Niton" in the port of Geneva serves as the point of origin with a height of 373.6 m.
