Available transformations
to EPSG:4326
EPSG:4326 - WGS 84

Selected transformation

Remarks: Replaced by S-JTSK (Ferro) to WGS 84 (3) (code 5242) in 2009.

Information source: OGP

Revision date: 2020-03-14

Attributes

Unit: degree (supplier to define representation)

Geodetic CRS: S-JTSK (Ferro)

Datum: System of the Unified Trigonometrical Cadastral Network (Ferro)

Ellipsoid: Bessel 1841

Prime meridian: Ferro

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: Geodesy.

Remarks: Initial realization, observed and calculated in projected CRS domain (CRS code 2065). Later densification introduced distortion with inaccuracy of several decimetres. In Slovakia has been deprecated and replaced by Greenwich equivalent, CRS code 4156.

Area of use: Czechia; Slovakia.

Coordinate system: Ellipsoidal 2D CS. Axes: latitude, longitude. Orientations: north, east. UoM: degree

Center coordinates
33.14 49.82

WGS84 bounds:
12.09 48.58
