     49This is a "how to" on using ossim-band-merge command line application to merge image files that represent individual bands into a single file.
     50
     51Prerequisite: Typically all images have the same dimensions and are relative to the same projection.
     52
     53Given you have band1.tif, band2.tif and band3.tif you can do:
     54
     55ossim-band-merge tiff_tiled_band_separate band1.tif band2.tif band3.tif rgb.tif
     56
     57Where "tiff_tiled_band_separate" is the output file type. You can do: ossim-band-merge by itself to get the usage with valid output image types.
     58
     59NOTE: The ossim library likes "tiled" image types as ossim is tiled in nature. So if you are going to feed the output file to another ossim application you should choose a tiled output format for speed.
