I want to calculate the area of regions covered by red color and regions covered by blue color.
I tried maximum likelihood classification using ArcMAP. I gave training sites from blue-colored regions as class 1 and training sites from red-colored regions as class 2 and training sites from white-colored regions as class 3.
The output has only 2 classes white and (red and blue) combined.
Though i gave different training sites for blue and red, the classifier combined red and blue. Why is that?
Is there anyother way to solve this issue?
