I have hundreds of multi-band, georeferenced JPGs that I need to convert to single band geotiffs. All images are black and white, so I only want one band to minimize file size.
Does anyone know tool that I can use to do this in bulk? I've tried copy raster, mosaic to new raster, and composite bands. None of them will give me a single band raster, although copy raster produces a nice 3-band geotiff. Thanks so much for any thoughts! I know there has to be a way to convert raster images to grayscale, I just can't find it.
