<p>Yes, but there are billing / bandwidth implications. I remember
we had it enabled, but CI cloning typically exhausted the allowed
free bandwidth.</p>
<p>Javier, maybe you can try using gdal_translate -scale X X X X -ot
UInt16 -co COMPRESS=DEFLATE -co TILED=YES -co PREDICTOR=2 with the
appropriate scaling values ?</p>
<p>Or gdal_translate -co DISCARD_LSB=X -co COMPRESS=DEFLATE -co
TILED=YES -co PREDICTOR=3 to nullify least signifcant bits of the
mantissa.<br>
