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).
Information source: Geodesy, Cartography and Cadastre Authority of Slovak Republic (UGKK SR).
Revision date: 2020-03-14
Unit: metre
Geodetic CRS: S-JTSK
Datum: System of the Unified Trigonometrical Cadastral Network
Ellipsoid: Bessel 1841
Prime meridian: Greenwich
Data source: EPSG
Information source: Research Institute for Geodesy Topography and Cartography (VUGTK); Prague, and Geodesy, Cartography and Cadastre Authority of Slovak Republic (UGKK SR).
Revision date: 2018-02-16
Scope: Cadastre in Slovakia.
Remarks: Equivalent to CRS code 2065 but referenced to Greenwich meridian. In SK remains legal system for cadastre, but for non-cadastral purposes replaced by S-JTSK [JTSK03] / Krovak (CRS code 8352). In CZ replaced by S-JTSK/05 / Modified Krovak, CRS code 5515.
Area of use: Czechia; Slovakia.
Coordinate system: Cartesian 2D CS. Axes: southing, westing (X,Y). Orientations: south, west. UoM: m.
