<div> </div>
</div>
<div>
<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>
