EPSG:3908 DEPRECATED

MGI 1901 / Balkans zone 6

Selected transformation

Method: Coordinate Frame rotation (geog2D domain)

Remarks: Derived at 5506 points across the Repulic of Serbia. May be taken as approximate transformation MGI 1901 to WGS 84 assuming ETRS89 is equivalent to WGS 84 within the accuracy of the transformation - see tfm code 7676.
