[Qgis-user] Working with second band of two-band GeoTIFF

[Fielding, Eric J (329A)]

I only recently switched to QGIS 3, so I am not sure whether I am missing something that was moved to a different place or the handling of raster layers changed. I am using 3.6.0 on a Mac. I have a two-band GeoTIFF image, and I want to run the Raster Calculator on the second band of the image. When I open the Raster Calculator, it only shows me band 1 of the image (image_name at 1). I tried forcing it to use band 2 with @2, but that did not work. I looked at layer Export->Save As and I don’t see a way to save the second band there. I finally went to the terminal and used “gdal_translate -b 2” to save the second band to a separate file. In QGIS 2, it showed me the two bands of the image in the Raster Calculator. Is there a way to do this inside QGIS 3?

Thanks,
                ++Eric
