[Gdal-dev] Combine multiple Tiffs into a single Tiff

[Thom DeCarlo]

Rob,
Someone else asked this quite a while back. Frank's response was:

>As long as the red, NIR and MIR are  the same size and for the same
>region you should be able to stack them with gdal_merge.py:
>
>gdal_merge.py -seperate red.tif nir.tif mir.tif -o stack.tif
>
>The -seperate flag means put each input into a seperate band.

But that didn't help me, since I didn't have python on my Windoze box.
Instead, I used "gdal_translate -of VRT" to create a *.vrt file for one of
the inputs. I then edited the vrt file to add the other bands (copied and
modified the <band> section). I then used gdal_translate to build a single
GTiff from the vrt file.

It was a bit roundabout, but it worked.
