Grn250m.gpd

; 250 m Greenland subset of 25 km Northern Hemisphere EASE-Grid.
; 250 m cells are nested exactly into 25 km Nl.gpd cells by a factor of 100.
; This projection uses a spherical earth model.
; Nl.gpd Col 262.5, Row 372.5 maps to the UL corner of the UL cell,
; and covers the specified 93 column x 87 row subset of Nl.gpd exactly.
; The map coordinates are in meters.
; 200540.2 is the N200correct.mpp scale converted to meters per map unit.
; Nl.gpd specifies 8 map units per cell.
; Nl.gpd specifies 360.0, 360.0 as the map origin column, row.
; 250 m Greenland subset of 25 km Northern Hemisphere EASE-Grid.
