Hi, I am using snap to make unsupervised classifications. I want to extract the spectral signature of the resulting classes. I do not realize how to do it

Hello everyone,
I’m a student of geodesy and geomatics and I’m supposed to do thesis on classification (supervised and unsupervised) of area near Novi Sad, Serbia. Since I’m new to s2tbx I’m having some problems. I already tried to do the unsupervised classification but the process didn’t finish even though it worked all night. I already tried to find some tutorials and user-guides that could help me, but I didn’t find anything usefull. So I was wondering if there is anyone who could help me i…
Or this one,
Hi,
Is it possible to build a spectral library based on Sentinel-2 data in SNAP and can the spectral library be used for classification also in SNAP, for example using Maximum-Likelihood Classifier?
Thanks for any tips
And,
Good morning everyone,
I am here to ask an opinion about a weird result I obtained from the spectral unmixing of a Sentinel2 image.
I have already worked with SMA on Sentinels, but this is the very first time something like this happens.
I selected three spectral signatures from the image (one for vegetation, one for soil and one for water).
I then launched the SMA, a Fully Contrained done with all the three spectral signatures. The output gave me three bands, one for each spectral signature…
