Hi,
I did something similar to what Doug suggested using the GDAL python
bindings to get the size, projection and pixel size of an image, then
cropping and re projecting to match using gdalwarp.
You can view the code at:

Hope this helps,
Thanks,
Dan

Content-Type: text/plain; charset="iso-8859-1" --j, I you wanted to
use the gdal utility programs , you can use gdalinfo to get the extent
of the first image and use gdal_translate -projwin with the
coordinates you captured from the first command. There are a couple of
ways to pythonify those two commands or other python methods into a
single script for batch processing, see
