[Gdal-dev] Batch export from a directory?

[Ivan Lucena]

Hi Jonathan,

As far as I can remember from the Science Data Processing Workshops, you
guys don't use Windows quite often at Greenbelt, but just in case you
are using Windows, you can open the Command Prompt and time this DOS
instruction:

C:\Data > for %i in (*.tif) do gdal_translate -of hfa %i %~ni.img

For more info type:

C:\Data > help for

 If you're using a bash shell, you might try a script along these lines:

====================
outputdir=/home/newdata
inputdir=/home/data

cd $inputdir
for raster in *; do

  gdalinfo $raster

  # If gdalinfo returned exit code 0,
  # we can assume its a valid raster image
  if [ $? = 0 ]; then

    # Assume the file prefix is everything before the first '.'
    prefix=` echo $raster | sed 's/\..*//'`

    # use gdal_translate to convert to ERDAS Imagine format
    gdal_translate -of "HFA" $raster ${outputdir}/${prefix}.img

  fi
done
=====================
