Technique
This mosaic is built from Landsat GeoCover 2000, 15-metre false colour
data (7,4,2 channels).
After several treatments allowing to rebuild the RGB (3,2,1) channels,
a colour treatment, which uses the RGB channels of the true-colour
Global Mosaic image, and a series of manual treatments are used
in order to get homogeneous colours and reduce the cloud cover percentage,
for underwater lands as well as oceans and coastlines.
This allows to combine accuracy and homogeneity of the GeoCover (7,4,2) mosaic, while obtaining a very realistic result in true colours.
