Maintaining band names in multiband raster objects
If you create a header for the file, using hrd(), with e.g. format='ENVI', then you should be able to open it in pretty much any GIS software. You have to point to the .gri file. That will preserve band names for when you re-import in R, and make the file possible to import in ArcGIS. I'm afraid you won't be able to get the band names outside of R though. Best regards, Lo?c

It is convenient for me, unfortunately it is not convenient for downstream users. They need a format that can be imported in (I hate to say it) ArcGIS. They are having trouble importing the native raster format into ArcGIS and I haven't had any luck either. Wade A. Wall US Army ERDC-CERL P.O.

It has the advantage of preserving layer names.

These names are interpretable and I would like to preserve them. Is there a way to specify band names for exported raster objects in R? I have seen posts suggesting it is not possible, but if they can be read, then they should be able to be written. Wade A. Wall US Army ERDC-CERL P.O.
