Hi all,
I have two rasters.
I need to output cells of one raster that are not present in the other. How 
would I go in order to achieve that using the raster calculator (i.e. avoiding 
Python)?
My logic so far is:
if A - B = A then output cells from A deriving from that evaluation and NoData 
everywhere else.
The problem is that in the raster calculator I can only evaluate the 
subtraction and the equality does not evaluate in the same way of the 
subtraction, even if computed in a different instance.
Is there a secret ingredient? Can my logic be rewritten differently? or am I 
way off?

Cheers
Davide
