Geodetic CRS: S-JTSK
Datum: System of the Unified Trigonometrical Cadastral Network
Ellipsoid: Bessel 1841
Prime meridian: Greenwich
Data source: EPSG
Information source: OGP
Revision date: 2020-03-14
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: Parameter values from S-JTSK to ETRS89 (1) (code 1622). Assumes ETRS89 and WGS 84 can be considered the same to within the accuracy of the transformation. Replaced by S-JTSK to WGS 84 (5) (code 5239).
Method: Position Vector transformation (geog2D domain)
Area of use: Czechia.
