I have the following gdal_retile command I am trying to run, but it errors on the --optfile:

gdal_retile.py -v -r bilinear -levels 8 -ps 512 512 -co "tiled=YES" -targetDir pyramid --optfile files.txt

   Unrecognised command option: -
   Usage: gdal_retile.py
        [-v] [-co NAME=VALUE]* [-of out_format]
        [-ps pixelWidth pixelHeight]
        [-ot  {Byte/Int16/UInt16/UInt32/Int32/Float32/Float64/
               CInt16/CInt32/CFloat32/CFloat64}]
        [ -tileIndex tileIndexName [-tileIndexField fieldName]]
        [ -csv fileName [-csvDelim delimiter]]
        [-s_srs srs_def]  [-pyramidOnly] -levels numberoflevels
        [-r {near/bilinear/cubic/cubicspline/lanczos}]
        [-useDirForEachRow]
        -targetDir TileDirectory input_files

Any idea why this does not work?

does it work without the optfile part? –  underdark Nov 6 '12 at 20:01
    
Can you show the contents of your files.txt? When using --optfile, the text file should contain the absolute path names. –  dmci Nov 7 '12 at 8:47

One alternative that may work for you would be to first create a virtual raster and then run gdal_retile.py

gdalbuildvrt -te xmin_vrt ymin_vrt xmax_vrt ymax_vrt -srcnodata "0 0 0" your.vrt ./path/*.tif

gdal_retile.py -v -r bilinear -levels 8 -ps 512 512 -co "tiled=YES" -targetDir pyramid -co "COMPRESS=LZW" -targetDir pyramid ./path/your.vrt

creative workaround! I like it. It won't generate pyramids for each input image though, just on the vrt, so may not work for some. See my answer for another alternative. –  matt wilkie Nov 9 '12 at 5:22

from my testing: Unrecognised command option: - is because a filename in files.txt has a dash in it. Enclose the names in quotes ("this-is-an-image.tif") and it will work fine.

Unfortunately the gdal_retile will not operate on multiple files ticket seems to be true; perhaps give it a bump. Here is a Windows cmd line snippet to work around that:

for %a in (*.tif) do gdal_retile "%a" -targetDir pyramids

to use in batch file double up the percents, e.g. %%a
