EPSG:8443

S-JTSK to ETRS89 (6)

Attributes

Geodetic CRS: S-JTSK

Datum: System of the Unified Trigonometrical Cadastral Network

Ellipsoid: Bessel 1841

Prime meridian: Greenwich

Data source: EPSG

Information source: Geodesy, Cartography and Cadastre Authority of Slovak Republic (UGKK SR).

Revision date: 2020-03-14

Steps of transformation: 8364 8367

Scope: Geodesy.

Remarks: Recommended method of a transformation from S-JTSK to ETRS89 in Slovakia. For reverse transformation see ETRS89 to S-JTSK (5) (code 8442). Both together replace S-JTSK to ETRS89 (4) (code 4827).

Area of use: Slovakia.
