Composite bands in raster calculator

Discussion created by mcorrell13 on Oct 4, 2013
Hello all-

I have 12 Landsat scenes I have made into composite band rasters, with 6 bands in each raster. I have clipped them down to the area in which I interested, and now need to log-transform and then calculate Z-scores for each cell in each of the bands of each of the 12 rasters. I have two questions here:

- when a composite band is entered into raster calculator, do all bands go through the same calculation?
- is there a commonly used way to calculate Z-scores on cells within a raster?

Thanks for the help.
