If I understand your question correctly, I might suggest an open source tool<br>
(GPL v3) for this job: pkcrop. It is part of pktools<br>
(<a href="http://pktools.nongnu.org" target="_blank">http://pktools.nongnu.org</a>), which is based on the GDAL API. By combining<br>
pkcrop with pkinfo (also in pktools), you could get what you want in a quite<br>
operational way. pkinfo allows you to define the proper bounding box, x, y<br>
resolution (pkinfo -i reference.tif -bb -dx -dy). The output can be directly<br>
used within pkcrop using $(command substitution). Not covered areas will<br>
have a nodata value. You can perform all steps in a one-liner: stacking a<br>
list of input images to a multi-layer image using the same bounding box and<br>
spatial resolution<br>
<br>
pkcrop $(pkinfo -i reference.tif -dx -dy -bb) $(for LS in landsat*.tif; do<br>
echo " -i " $LS;done) -o stacked.tif<br>
