In this sequence, an image of the biosphere of the earth is overlaid onto a sphere with both topographic and bathymetric relief. The ocean biospheric data is a composite of 31,352 4 km resolution Coastal Zone Color Scanner (CZCS) scenes from November 1978 through June 1981. The land vegetation patterns are derived from three years of daily images from the visible and near-infrared sensors of the NOAA-7 satellite.
