<p>Matt,</p>
<p>There has been an enhancement in gdalwarp to support writing
directly to drivers, like COG, that supports only the CreateCopy
mode. So you don't need the 2 step process and can directly
gdalwarp -of COG (it will more or less do the 2 steps internally)</p>
<p>If you output to regular GTiff, the 2 step process might be
needed to get the best compression</p>
<p>Even<br>

<p class="MsoNormal">A few years ago it was best practice to
follow a gdal warp process with translate in order to get
better compression, and even overall speed although extra disk
write is involved. Is this still the case? and when using COG
output driver? e.g.</p>
