EPSG:25834 — ETRS89 / UTM zone 34N

Source: EPSG Dataset via PROJ 9.5.1 · Updated

Summary

EPSG:25834 (ETRS89 / UTM zone 34N) is a projected coordinate reference system on the European Terrestrial Reference System 1989 ensemble datum using the Transverse Mercator method, with coordinates in metres. Area of use: Europe between 18°E and 24°E: Bulgaria; Croatia; Italy - onshore and offshore; Norway including Svalbard - onshore and offshore. The datum is an ensemble with about 0.1 m accuracy, so precise work should name a specific realization.

Example coordinates

A WGS 84 point at longitude 22.5°, latitude 50.0° (inside the area of use) has these coordinates in EPSG:25834:

Computed with PROJ using the EPSG default operation: axis order change (2D) + Inverse of ETRS89 to WGS 84 (1) + UTM zone 34N.
AxisValueUnit
E607,498.493m
N5,539,708.757m

At this point the projection scale factor is 0.99974193 and the grid convergence is +1.149176°.

A PROJ string cannot carry every EPSG detail (axis order, datum ensemble, transformations). Prefer WKT2 or the EPSG code itself.

Datum shift from ETRS89 to WGS 84 (1) (EPSG accuracy 1 m), the best single Helmert operation for this area of use. Where PROJ prefers a grid-based or multi-step operation (see the table above), results can differ by up to that operation's accuracy.
