Thanks Chaitanya.
One more doubt.
I would like to know whether any GDAL application supports resizing an image (with no projection details) using lanscoz resampling method. I looked at gdal translate but could not find the option to change the resampling method. Kindly let me know if there is any option.
Thanks and Regards
J.Viswanath
