EPSG:3412 DEPRECATED

NSIDC Sea Ice Polar Stereographic South

Attributes

Unit: metre

Geodetic CRS: Unspecified datum based upon the Hughes 1980 ellipsoid

Datum: Not specified (based on Hughes 1980 ellipsoid)

Ellipsoid: Hughes 1980

Prime meridian: Greenwich

Data source: EPSG

Information source: US National Snow and Ice Data Center.

Revision date: 2009-06-02

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 3976 for geodetically preferred alternative.

Area of use: Southern hemisphere - south of 60°S onshore and offshore - Antarctica.

Coordinate system: Cartesian 2D CS for south polar azimuthal lonO 0°E. Axes: X,Y. Orientations: X along 90°E, Y along 0°E meridians. UoM: m.
