(1) Higher the wavelength, higher the correlation
(2) ALOS is systematically better correlated with QuickBird than with LANDSAT,in spite of similar spectral ranges for these latter

(3) Correlation is very low in relief areasSun elevation is different, 26° for LANDSAT, 37° for QuickBird, and 45° for ALOS
(4) For flat areas (carbonates), correlation is better for dolomite than for limestoneImportance of the contact metamorphic zone (cooked carbonates). Investigation is in progress.
