I have created a set of images from one spectral image using band math. I now want to assemble these into a single, multi-channel image in order to examine the results using the n-dimensional visualizer. Neither the original image nor any of the computed images were geo-registered, so the layer stacking tool will not work. However, the images are all the same size, resolution, etc. since they are derived from a single source. Is there a tool to build a multi-channel image out of this type of data?
