EPSG:3873

ETRS89 / GK19FIN

Attributes

Unit: metre

Geodetic CRS: ETRS89

Datum: European Terrestrial Reference System 1989 ensemble

Data source: EPSG

Information source: National Land Survey of Finland; http://www.maanmittauslaitos.fi

Revision date: 2020-03-30

Scope: Cadastre, engineering survey, topographic mapping (large scale).

Remarks: Replaces ETRS89 / ETRS-GK19FIN (CRS code 3126). (For medium scale mapping and country-wide work use ETRS89 / TM35FIN(N,E), code 5048).

Area of use: Finland - nominally onshore west of 19°30'E but may be used in adjacent areas to east if a municipality chooses to use one zone over its whole extent.

Coordinate system: Cartesian 2D CS. Axes: northing, easting (N,E). Orientations: north, east. UoM: m.
