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: Derived from concatenation of ETRS89-CHE CHTRF95] to ETRF89 (1) (CT code 11308) with ETRF89 to ETRF2000 (CT code 10988) reduced to epoch 1993.0. Scale difference in ppb and scale difference rate in ppb/yr where 1/billion = 1E-9 or nm/m. 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: Time-dependent Position Vector tfm (geocentric)
Area of use: Liechtenstein; Switzerland.
