EPSG:3911 DEPRECATED

MGI 1901 / Slovenia Grid

Selected transformation

Method: Coordinate Frame rotation (geog2D domain)

Remarks: Parameter values from MGI to Slovenia 1996 (12) (tfm code 8689) assuming Slovenia 1996 and WGS 84 can be considered the same to within the accuracy of the transformation.

Information source: Berk and Komadina in GIS v Slovenije volume 10, 2009-2010, 291-299, Ljubliana. Also in Berk & Boldin (2017) Slovenian Coordinate Reference Systems in GIS Environment, Geodetski Vestnik 61(1), 91-101 using Position Vector transformation.
