</div>> 1. Can I store overviews in a different path than the original raster<br>
<div class="im">> path? The original path can be in a read only folder like an optical disc.<br>
<br>
</div>This should be possible by using the GDAL PamProxy mechanism, but I'ma afraid<br>
this is very lightly documented. See <a href="http://trac.osgeo.org/gdal/ticket/2432" target="_blank">http://trac.osgeo.org/gdal/ticket/2432</a> for<br>
some elements.<br>
<br>
> 2. Can I build overviews of an entire VRT tile index ?<br>
<br>
gdaladdo on a VRT should work.<br>
