<p>Hi,</p>
<p>Before I go to my default mode and python my way through this, is
there a plugin that would permit me to perform batch operation on
all the layers found in a single .gpkg file? My geopackages
contain hundreds of layers (from autocad) (contain identical data
structures) and I would like to do things like:</p>
<ul>
<li>Perform field calculator operations on each layer within the
geopackage<br>
</li>
<li>Split all geopackage layer with a field<br>
</li>
<li>Merge multiple layers in a new geopackage</li>
</ul>
<p>I guess FME would be another way out? I there an OpenSource
equivilant to this? (I have a home version but I need to respect
the license for this one.)<br>
</p>
