Dear List, I have made a series of unsupervised classifications from various geographic substrata of a Landsat ETM scene, and would now like to combine them into a single classification map. Here's the story so far: * Each stratum (there are three) has been independently classified, producing between 78 and 113 spectral clusters per stratum. * I've re-named each spectral cluster into an information class using "Edit Class/Region Color and Name", producing the same 20 or so classes for each stratum. Obviously, the original class numbers don't necessarily match the same information classes from stratum to stratum. * I'd now like to recombine the three strata back into a single image, using the renamed information classes and NOT the original class numbers. How best to do it? Please don't say that I have to come up with formulae for each spectral cluster that says "if i1=77 then 15 else null" and so on...
