I am using the batch convert utility in my QGIS (ver. 3.18; Zurich) within
the GDAL Toolbox, especially its "Translate (Convert Format)" utility under
"Raster Conversion".
While this utility converts all the files from .tif to .rst & .rdc very
quickly and accurately, it does not have any scope of changing the pixel
resolution
Hi Amal Kar,
the "Translate (Convert Format)" GDAL processing algorithm is based on
the GDAL "gdal_translate" utility [1] as stated in the algorithm help
page [2].
The "gdal_translate" utility has various parameter to set the output
resolution [3] and the resampling method [4].
The "Translate (Convert Format)" algorithm exposes in the GUI only a
subset of the "gdal_translate" utility parameters.
Anyway you could provide additional parameters using the "Additional
command-line parameters" algorithm parameter.
Another way could be to use the "Warp (reproject)" GDAL processing
algorithm [5] which is based on the GDAL "gdalwarp" utility and which
exposes in the GUI the both the output resolution and the resampling
method parameters.
Best regards.
