Maximum Likelihood and extract signature

Hi everyone, I’m a new Snap user and i don’t have much practicality yet. How does algorithm of MLC work in SNAP? It’s possible to extract the spectral signature as on Erdas?

regarding the spectral signature, please have a look at the documentation:

Regarding the supervised classification, descriptions are given here:

Thank you for the reply.

When I open the Spectrum View appears “Collecting spectral information”. It’s possible to extract the Signatures to use them in other programs? Example (file.sig)

In those page I have not found nothing about the algorithm of MLC

yes, either with the export button in the spectrum view grafik, or alternatively with the pin manager

Maximum Likelihood is not exclusively used in SNAP. Here is a very well made tutorial:

Thank you very much!
