EPSG:15987 DEPRECATED

MGI to Slovenia 1996 (6)

Attributes

Geodetic CRS: MGI

Datum: Militar-Geographische Institut

Ellipsoid: Bessel 1841

Prime meridian: Greenwich

Data source: EPSG

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

Revision date: 2008-09-23

Scope: Transformation of coordinates at 0.3m 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 - Dolenjska (Lower Carniola).

Description: (0,)
