EPSG:11308

ETRS89-CHE [CHTRF95] to ETRF89 (1)

Attributes

Geodetic CRS: ETRS89-CHE [CHTRF95]

Datum: Swiss Terrestrial Reference Frame 1995

Ellipsoid: GRS 1980

Prime meridian: Greenwich

Data source: EPSG

Information source: IOGP

Revision date: 2026-02-10

Scope: Merging of spatial data referenced to different national realizations of ETRS89 at the sub-decimetre level of accuracy.

Remarks: Accuracy is approximately 1cm at the ETRS89-CHE [CHTRF95] anchor epoch of 1993.0, but deteriorates with time due to tectonic deformation and/or glacial isostatic adjustment.

Method: Geocentric translations (geocentric domain)

Area of use: Liechtenstein; Switzerland.
