Select one of your classified images as the Input File. identical landcover categories have been generated for both ‘before’ and ‘after‘ classified thematic images, the ‘before’ and ‘after‘ raster images are spatially coregistered (same geographical extent) with each other, the ‘before’ and ‘after‘ raster images have the same spatial resolution (e.g. Please review my response in another topic discussion for detailed instructions. I'm doing post-classification comparison with two supervised classifications of 1 m spatial resolution on ERDAS Imagine. All satellite data were studied by assigning per-pixel signatures and differentiating the watershed into five classes on the bases of the specific Digital Number (DN) value of different landscape elements. The matrix is square, with all correct classifications along the upper-left to lower-right diagonal. Land cover nomenclature is classified according to the CORINE (Coordination of Information on Before the change detection process, ERDAS IMAGINE recode tool was used to recode the class values for both previously classified images to ensure that classes in both images had the same codes.
