CH1903+ to ETRS89-CHE [CHTRS95] (1)

Attributes

Geodetic CRS: CH1903+

Datum: CH1903+

Ellipsoid: Bessel 1841

Prime meridian: Greenwich

Data source: EPSG

Information source: Bundesamt für Landestopografie swisstopo; www.swisstopo.ch. Aufbau der Landesvermessung der Schweiz 'LV95' Teil 3: Terrestrische Bezugssysteme und Bezugsrahmen. L+T 1999.

Revision date: 2026-07-21

Scope: Transformation of coordinates at 0.1m level of accuracy.

Remarks: LV-95 Parameters. Also used with reduced accuracy as transformation from CH1903 to CHTRS95 - see code 11782. This transformation is also given as CH1903+ to ensemble-based ETRS89 (code 1647).
