Hey have a probably very stupid, ignorant and totally dense question
but.. its driving me mad!

Here goes,
If I have say an image of count values which I want to convert to
something say albedo. I have no equation just a table of values which
say that count 100 equals a value etc.. (I know there is somewhere here
Iï¿½m being dense!) So basically (!) how can get the image array to look
for its dn value in the first column of the table and then replace or
generate a new array with the new albedo values in.

Anyone got any advice? Help? Wonderful pearls of wisdom?

Thanks in advance

alex
