I search for an argument (which I could cite, ideally) to support my decision to exclude Thermal band 6 from Maximum likelihood classification (MLC) of Landsat (5-7) imagery. To my knowledge, the thermal band 6 is suggested to exclude from MLC because of its coarser spatial resolution (~ 120 m), comparing to another bands (30 m).
Can you suggest me some papers resulting this?
The only one I've found is: http://www.isprs.org/proceedings/XXXIV/part1/paper/00077.pdf ... a classification utilizing all of the TM bands (excluding the thermal band due to its coarse spatial resolution) ...
Do you have suggestions for another paper/handbook?
