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 - onshore Primorska and Notranjska (Inner Carniola).
