Hi,
You are right but when I try to check the data processing, there is no any
compression. On my computer, it is similar to your situation. I guess most
nodata values are over 32760, so maybe I can list all o

Dear Ms./Mr. Jukka
Thank you for your reply. I try to delete the -srcnodata 32767, but it still
doesn't work.
I have attach a part of raster, in this email.
Thanks for your hel
use gdal_translate with
-srswin or -projwin for that.

Hi all,
Hi all,
I am going to use gdalwarp to resample a 800x800 wgs84 image but I did not

units"?
This is my input image:
Size is 800, 800
