I stumbled upon this article: Spectral Angle Mapper Application Using Sentinel-2 in Coastal Placer Deposits in Vigo Estuary, Northwest Spain

It shows the usage of SNAP’s Spectral Angle Mapper in practice.

Maybe it is worth to add it to the documentation? @diana_harosa

Just a question - anybody has used the SAM tool with Landsat 8 OLI data?

Thank you.
