Advanced Product - Alteration Index

Alteration Index is the resulting raster image after all the processes, shows the probability of 0 to 100, for each pixel, of containing alteration.

We only mark as alteration those pixels with a very high probability (the polygons in red color).
However, this image provides other patterns and trends, interesting information to contrast with other field observations, such as NW-SE lineation (marked in green).
