EPSG:3975 WGS 84 / NSIDC EASE-Grid Global
Projection: Cylindrical Equal-Area Latitude of the origin: 0° Longitude of the origin
(central meridian):0° Standard parallel: 30° Scaling factor: 1 False eastings: 0 False northings: 0 Ellipsoid: WGS84 Datum: WGS84 Units: meters Global extent
(minx, miny, maxy, maxy):-17334193.540, -7344784.825,
17334193.540, 7344784.825NOTE: This map projection is similar to the one used in NSIDC's EASE-Grid data products. Rather than using a custom sphere for its datum, however, it uses WGS84.
