ETRS89-CHE [CHTRS95]

Attributes

Unit: metre

Geodetic CRS: ETRS89-CHE [CHTRS95]

Datum: Swiss Terrestrial Reference System 1995

Ellipsoid: GRS 1980

Prime meridian: Greenwich

Data source: EPSG

Information source: Bundesamt für Landestopografie swisstopo; www.swisstopo.ch

Revision date: 2026-07-21

Scope: Geodesy.

Remarks: Referenced to ETRF93 at epoch 1993.0. First realized through CHTRF95 and subsequently CHTRF98, with an aim to re-measure every 6 years. CHTRF98, CHTRF2004, CHTRF2010 and CHTRF2016 are all within 2cm of CHTRF95 and used for scientific applications, but for most practical purposes differences are considered insignificant. For CRS used for topographic and cadastral purposes see CH1903+ (CRS code 4150).

Area of use: Liechtenstein; Switzerland.

Coordinate system: Cartesian 3D CS (geocentric). Axes: geocentric X Y Z. Orientations: X and Y in equatorial plane, X positive through intersection with prime meridian, Y through 0°N 90°E. Z axis parallel to mean earth rotation axis and positive towards North Pole. UoM: m.
