EPSG:3921

MGI 1901 to Slovenia 1996 (4)

Attributes

Geodetic CRS: MGI 1901

Datum: MGI 1901

Ellipsoid: Bessel 1841

Prime meridian: Greenwich

Data source: EPSG

Information source: Geodetska uprava Republike Slovenije, http://www.gu.gov.si

Revision date: 2009-03-12

Scope: Transformation of coordinates at 0.5m level of accuracy.

Remarks: Info source also gives a separate reverse tfm with slightly different parameter values. Given the tfm accuracy these differences are not significant and this tfm can be considered reversible.

Method: Coordinate Frame rotation (geog2D domain)

Area of use: Slovenia - east of 14°30'E and south of 46°09'N.

Description: (0,)
