I have a multi-band raster and I am using
gdal_translate -b 1 -scale 30 30 landscape.lcp band_1.tif
to get a single band in tif format. Now if I check values of band 1 in landscape.lcp, those lie between 0 -270. But if I check values in band1.tif, the values lie between -32768- 32767. Any pointer how to keep the original values in the band_1.tif file.
You can do this through Spatial Analyst.
Adding separate bands is very simple. When you are adding layer, go to your tiff and instead of adding, double-click on it. You will enter into its bands and now you can add these bands separately.
So, from this
you will enter into this
Then you can use Raster calculator to do the sum. Open it from the Spatial Analyst toolbar.
And just write your equation for the 3 bands.
Then you will get a temporary raster which you can save on your computer.
Hope this is what you need.
I also couldn't find a way to do it in one step... but using -sds like you did, followed by a gdal_merge.py -separate should work https://gdal.org/programs/gdal_merge.html#cmdoption-gdaladdo-separate
https://gdal.org/programs/gdal_translate.html#cmdoption-gdal-translate-sds
So this should work for you:
gdal_translate -sds input_file.hdf tmp_outs.tif
gdal_merge.py -separate -o final_output.tif tmp_outs*tif
rm tmp_outs*tif
if your HDF5 subdatasets are different datatypes, specify which output type you want with gdal_merge.py -ot Float32 ...
Just to reference here what those options mean:
-sds
Copy all subdatasets of this file to individual output files. Use with formats like HDF that have subdatasets.
-separate
Place each input file into a separate band.

It seems like you don't want to rescale the input pixel values (
-scale) but set the target resolution (-tr), so try with:
