Unsupervised classification

Question asked by LKomaromi on Dec 2, 2016

Hi there,

 

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: 

What are the band designations for the Landsat satellites? 

 

Thanks for your help in advance.
