Separate bands from image from composite of bands

[DiegoMendes_Rodrigues]

Colleagues,

I have an image (.img) which is a composite of bands with 12 bands from a Sentinel-2.

In Model Builder, I need to use this image with the 12 bands, and then separate them, to use in calculations.

How can I do this band separation in Model Builder?

Regards,
Diego

Hi Diego,

Have you tried "Extract Band" function? Extract Band function—ArcGIS Pro | Documentation

The image T23KLS_20211107T131251.img is a user-defined input of the model in the Model Builder.

How can I include the "Extract Band" in the model?

Band separation will be performed in the future when the end user runs the model.

A couple of thoughts:
You should be able to navigate into the multiband image to access each band using paths.
Another thing to look into is the Select Data tool, which is used unpack data out of containers like multiband images and feature datasets.
