Hello!

I try to calculate NDVI using Raster Calculator:

But result has only three values (and three colors): -1, 0 and +1.

What am I doing wrong?

Thanks!

The integer using an 8 bit pixel type for DN values from 0 - 255 in whole numbers.

The float (32 bit) allows for decimals.

The map algebra is Float ("%file.tif%")
