My problem is I am supposed to classify an image of K2 glacier...it is CHRIS data/ However, my proff. expects me to get creative out of this boring snow data. So can anyone suggest me how i should start and what I can classify in this image..i have to submit a "creative" output within 10 days to get a distinction..any form of suggestion is appreciated. seriously what can one classify in snow? and i do not even know which tools of ENVI are useful for me.
