Geodetic CRS: ETRS89-CHE [CHTRS95]
Datum: Swiss Terrestrial Reference System 1995
Ellipsoid: GRS 1980
Prime meridian: Greenwich
Data source: EPSG
Information source: OGP
Revision date: 2021-09-23
Scope: (null/copy) Approximation for medium and low accuracy applications assuming equality between plate-fixed static and earth-fixed dynamic CRSs, ignoring static/dynamic CRS differences.
Remarks: For many purposes CHTRS95 can be considered to be coincident with WGS 84.
Method: Geocentric translations (geog2D domain)
Area of use: Liechtenstein; Switzerland.
