I have stacked layer (from ERDAS) of Landsat 1-5 and 7, bands. I want each of the bands in a separate layer. How can I do that?
Spatial Model Editor in erdas can be used to solve your problem. I already made a simple model, you can download from this gmdx model .
I know this an old question, but here is another way to unstack multiband-image. The solution is done using QGIS with Orfeo toolbox installed. You can use
split image tool from Orfeo toolbox. The
Split Image, as you can see below, will split the multiband-image that you have into separate images, and each image has one band.
You need to specify an output filename. The output filename will be used to get the prefix and the extension of the output images to write.
In the example above, I just put
Image.tif. You can choose any name you prefer.
However, Orfeo toolbox is not downloaded by default into QGIS. You need to download it separately, or better use OSGeo4W advanced install to download Orfeo toolbox from there.
I don't know if you have already solved this but I had the same issue as your are...but here is the solution for you to unstack your bands to individual band you want.
