<p class="MsoNormal">I can see how spatially filtering the input (-spat) is useful, but I don't want to clip the geometries (other than clipping by tile edges that MVT driver does by default). What I'm after is spatial filtering of the output tiles based on
each tile extent.<o:p></o:p></p>

<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">So to further clarify, I could do the translation using -spat <ROI> and then iterate over all of the generated MVT files and delete the ones whose tile extent does not intersect with <ROI>. But that would waste resources in a big way.<o:p></o:p></p>
