Name: S-JTSK to ETRS89 (6)
Grid Files: Slovakia_JTSK03_to_JTSK.LAS Slovakia_JTSK03_to_JTSK.LOS
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).

Unit: metre
Geodetic CRS: S-JTSK
Datum: System of the Unified Trigonometrical Cadastral Network
Ellipsoid: Bessel 1841
Prime meridian: Greenwich

Scope: Cadastre in Slovakia.
Remarks: Equivalent to CRS code 2065 but referenced to Greenwich meridian. In Slovakia remains the legal system for cadastre but for non-cadastral purposes replaced by CRS 8352. In Czechia remains the legal system but see CRS 5515 for a scientific working system.
