Hi everyone,
I am new to GDAL and I need some help on how to do re-sampling
(programmatically).
I have 30mx30m Geotiff images and I'd like to resample them into 25mx25m
Geotiff images.
Any help on this is very appreciated.
Belaid,
One approach to do this would be a command like:
gdalwarp -tr 25 25 input.tif output.tif
This resamples to 25x25 meter pixels with the default (nearest neighbour)
resampling kernel. You might also want to use a fancier resampling kernel,
such as cubic convolution:
gdalwarp -r cubic -tr 25 25 input.tif output.tif
More details are available at:

Best regards,
