Maximum Likelihood and extract signature

[Fernando]

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:

• Supervised and unsupervised classification, Sentinel 2
• Rndom forest classification steps

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 , or alternatively with the pin manager

Maximum Likelihood is not exclusively used in SNAP. Here is a very well made tutorial: http://statgen.iop.kcl.ac.uk/bgim/mle/sslike_1.html

Thank you very much!
