Peru Mineral Mosaic SAM Classification

Goal

In this tutorial, the user will learn how to use the Breeze GEO software to classify minerals using SAM spectral angle mapper.

The training data

The training data consists of 16 different mineral from Peru in a 4x4 mosaic. The spectral range is between 414.8-2498.1.

Download and import tutorial image data

Start Breeze

Press “Tutorial” and choose “Peru Mineral Mosaic SAM Classification” in the drop-down menu and press OK.

After the tutorial data is downloaded a project will appear in Breeze Geo.
