Tiling and Image

[Rahkonen Jukka]

Hi,
 
You cannot use tileindex shapefile as an image catalogue input for gdal_translate.  However, you can reach the same effect by creating a GDAL virtual dataset (GDAL/VRT) from your images and using that as input.  There was discussion about this some time ago under title "Palletizing Bulk Tiled Imagery", search the archive for details.
 
Regards,

Hi Kevin,
I don't think so.  But you could grab the image from MapServer 
directly in, say, a TIFF format instead or via WMS if you can find a 
way with gdal_translate.

Yes, using the -srcwin or -projwin parameters.
