EPSG:3411

NSIDC Sea Ice Polar Stereographic North

Attributes

Unit: metre

Geodetic CRS: Hughes 1980

Datum: Hughes 1980

Ellipsoid: Hughes 1980

Prime meridian: Greenwich

Data source: EPSG

Information source: US National Snow and Ice Data Center.

Revision date: 2023-06-29

Scope: Polar research.

Remarks: The datum is unspecified. Uncertainty in location of over 1 km may result; at the coarse resolution and very small scales for which this system should be used this uncertainty may be insignificant. See CRS 3413 for geodetically preferred alternative.

Area of use: Northern hemisphere - north of 60°N onshore and offshore, including Arctic.

Coordinate system: Cartesian 2D CS for north polar azimuthal lonO 45°W. Axes: X,Y. Orientations: X along 45°E, Y along 135°E meridians. UoM: m.
