This has been discussed recently. See http://lists.osgeo.org/pipermail/gdal- dev/2011-January/027567.html and the following messages. (I'd note that if you process a pixel interleaved image, there are optimizations in the GTiff driver to make the fetching of other bands almost 'free' if you read block by block, so there's probably little to gain, but the results of your experiments are welcome) > > > Regards, > Stefano _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
