For those frustrated by the lack of colour images, here's my recipe: Download the L2 and L7 images. These are Red and Blue. Concoct a synthetic green from (L2+L7)/2. I find a tweak is required to put a tad more green into it, but it's close. Here is a sample synthetic colour from L2 & L7 only And here the equivalent from L2, L5, and L7. Of course, neither is true colour, but we can begin to fiddle - lots less blue, a bit more red, and dial down the saturation a lot... -------------------- - Nick ===================================== Nick Hoffman Mars Specialist 3D-GEO Pty Ltd Melbourne Australia http://whitemars.com "First they ignore you, then they laugh at you, then they fight you, then you win." - Mahatma Gandhi (1869-1948) =====================================
