Lambert Equal-Area EASE-Grid Projection

Northern Hemisphere

Southern Hemisphere

• Tiles are 951 pixels by 951 pixels and 10 degrees by 10 degrees. Half of the tiles (313) are in the north polar grid and the other half are in the south polar grid.
• The north polar grid tile coordinate system starts at (0,0) (horizontal tile number, vertical tile number) in the upper left corner and proceeds right (horizontal) and downward (vertical). The tile in the bottom left corner is (18,18).
• The south polar grid tile coordinate system starts at (0,20) and the tile in the bottom left corner is (18,38).
• The polar grids are based on the Lambert Azimuthal Equal Area map projection centered on each pole. The grids are compatible with the NSIDC EASE-Grid.
