Great many thanks!

Okay - closer to the second one. Basically, a lookup table (http://en.wikipedia.org/wiki/Lookup_table) allows for a simple "translation" of one value to another. Say you have a grayscale image of, for the sake of argument, a map of a hilly landscape. Light gray = higher, dark gray = lower. Grayscale in this instance can be defined as 255 shades of gray, 0 darkest, 255 lightest. We now want a color image that shows tops of hills in red, valleys in blue. So the lookup table features, for example, grayscale value less than 50 = shades of blue, grayscale values over 200 = shades of red.

My real problem here is with "auf die Farbwerte abgebildet werden" rather than just with "abgebildet". Does it mean "how the grayscale values in the data will be represented as false color"/"how the grayscale values in the data will be converted into color"?
