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: OGP
Information source: US National Snow and Ice Data Center.
Revision date: 2009-06-02
Scope: Polar research. Used for small scale mapping of DMSP SSM/I microwave satellite imagery.
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.
