[gdal-dev] gdal_translate syntax input separate R, G, B output combined RGB

[Chaitanya kumar CH]

Dear Greg,

I am new here. So correct me if I am wrong.
Try using Virtual Format files. More info at
http://www.gdal.org/gdal_vrttut.html

You should be able to create a VRTRasterBand for each band with the
corresponding source.
gtif_RGB.vrt would look something like this...

<VRTDataset rasterXSize="1172" rasterYSize="1864">
  <VRTRasterBand dataType="Byte" band="1">
    <SourceFilename relativetoVRT="1">gtif_R.tif</SourceFilename>
  </VRTRasterBand>
  <VRTRasterBand dataType="Byte" band="2">
    <SourceFilename relativetoVRT="1">gtif_G.tif</SourceFilename>
  </VRTRasterBand>
  <VRTRasterBand dataType="Byte" band="3">
    <SourceFilename relativetoVRT="1">gtif_B.tif</SourceFilename>
  </VRTRasterBand>
</VRTDataset>
