Geodetic CRS: NGO 1948
Datum: NGO 1948
Ellipsoid: Bessel Modified
Prime meridian: Greenwich
Data source: EPSG
Information source: OGP
Revision date: 2020-03-14
Scope: (null/copy) Approximation for medium and low accuracy applications assuming equality between plate-fixed static and earth-fixed dynamic CRSs, ignoring static/dynamic CRS differences.
Remarks: Parameter values from NGO 1948 to ETRS89 (1) (code 1653). Assumes ETRS89 and WGS 84 can be considered the same to within the accuracy of the transformation.
Method: Position Vector transformation (geog2D domain)
Area of use: Norway - onshore.
