World Satellite 2 km resolution
The satellite image of the World at 2 km per pixel resolution gives an image 21600 pixels wide by 10800 pixels high giving an image 144 inches wide at 150 dpi. The uncompressed file size is 700 MB. Projection is defined as Plate Carree / Geographical / Linear.
The satellite systems provide frequent global coverage and generate realistic land surface colour for anywhere in the world.
Ocean color is derived from a combination of ocean depth and ocean chlorophyll observations. Polar areas covered by sea ice are derived from individual optical images.
