EPSG:3912

MGI 1901 / Slovene National Grid

Selected transformation

Method: Coordinate Frame rotation (geog2D domain)

Remarks: Derived at 479 nodes of Delauney triangulation generated from 1958 control points. Replaces MGI 1901 to Slovenia 1996 (1) (code 3916). May be taken as approximate transformation MGI 1901 to WGS 84 (see code 8688).

Attributes

Unit: metre

Geodetic CRS: MGI 1901

Datum: MGI 1901

Ellipsoid: Bessel 1841

Prime meridian: Greenwich

Scope: Cadastre, engineering survey, topographic mapping (large and medium scale).

Remarks: In Slovenia replaces MGI 1901 / Balkans zone 5 (D48 zone 5) (CRS code 8677) and MGI 1901 / Slovenia Grid (CRS code 8686). Replaced by D96/TM (CRS code 3794) although old cadastral records still related to D48/GK.

Area of use: Slovenia - onshore and offshore.

Coordinate system: Cartesian 2D CS. Axes: easting, northing (Y,X). Orientations: east, north. UoM: m.
