I am about to classify Landsat images using unsupervised classification. I have 16 images (1 image/year) from which I intend to extract glacier surfaces only.
The first step would be to create composite images consisting the relevant bands for each year. My question is which bands should I combine from each Landsat scenes to get a composite image that can be used as input raster for unsupervised classification? I am looking at the 30m resolution bands only.
Here are the band designations for each satellite:
Thanks for your help in advance.
