Similar question here: How to combine more iterations of a for loop to bands of a single raster?
I have downloaded over 100 Landsat MSS and TM images with separate bands, and I want to combine bands as a single file with multi-bands by the composite bands function. However, I got stuck in using the ArcGIS model builder. As an example for TM images, my idea was to use six submodels (iterate raster) to gather 6 TM bands (except thermal), and combine bands, but each iterate raster function only outputs one raster, instead of multiple rasters. The files were organized by years. In other words, each year may have MSS and TM bands together, but MSS and TM bands did have specific file names.
Any further suggestion?
