I'm trying to use individual bands from a multi-band TM image (IMG file) within the raster calculator in ArcGIS 10 (SP2/3). I can add individual bands to my MXD, but raster calculator will only use Band 1 regardless of how I reference the layers from the MXD.
Using something like
"TM_Image.img - Layer_3" - 0 in the raster calculator will run, but will use Band 1.
Using the full path to the image works correctly but is unwieldy for longer expressions/paths. Like
"X:\TM_Image.img\Layer_3" - 0
I think this worked in earlier versions of Arc 10, but no longer on SP 2 or 3. Thanks for any advice on syntax that I might be missing!
