Very helpful. Clear presentation. Thank you.

good video, i have a question,
What bands do i have to select to use SAM?
The bands with high reflec or absorb...? Thank you , i suscribe.

Interesting tutorials especially on Algorithms,cool! Please give more and load some your data for a practice

[@agholli9924]

is there any difference if we do atmospheric correction before we do this ?

thanks very much, very helpful tutorial

Hello,
I really love you very enrichisants tutorials and I hope you continue this work
I am a student in geology, I have a satellite Image aster.
I aim to delineate areas of hydrothermal alteration.
I would be very grateful if you can provide me the correct and reliable method to arrive at my goal.
Thank you

For spectral angle mapper classification, first, the image pixel values should be converted to atmospherically corrected reflectance data, otherwise, you will have misclassification.
