[Qgis-user] Amal Kar - India - Batch conversion of files for raster layer format from geotiff to idrisi, and simultaneously from a higher pixel resolution to a lower one.

[Amal Kar]

Dear Community Members,
I am currently trying to make use of a series of Raster data files from
Modis satellite sensors that are available in Geotiff format (.tif) and in
the pixel resolution of 500-m.
I downloaded the files from a USGS website, and wanted to convert each file
into an Idrisi raster format (16 bit integer elevation data in .RST & .RDC
files), and in 1-km pixel resolution.
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 (i.e., from pixel width & height of 0.00417 arc degrees for 500
m pixels to the width & height of 0.008333333 arc degrees for the desired
1-km pixels).
When i do the conversion of files individually by opening each .tif raster
file and then exporting each ("Save as") to idrisi format, it opens a new
window of "Save Raster Layer as....", where the options are for changing
the "Resolution", both horizontal and vertical.
However, changing each data file through this process, especially when i am
dealing with a few hundreds of daily satellite data files, is very
cumbersome. There must be some clickable tool  hidden within the Tool Box,
which i am too naive to understand and pick up (i am NOT computer-savvy,
although i use it more often for digital analysis of my earth surface data
in GIS).
I shall be highly grateful if you can lead me to the appropriate tool in
my  QGIS (ver. 3.18; Zurich), which can be easily followed.
Thanking You for Your patience, and with Kind Regards,
amal kar.
