<div class="elementToProof">At <a href="https://github.com/larsop/find-overlap-and-gap">https://github.com/larsop/find-overlap-and-gap</a></div>
<div class="elementToProof">we have code that checks for overlaps and gaps on simple feature polygons and creates a spatial tables with the results. We have used this code on tables with millions of rows.</div>
<div class="elementToProof"><br>
</div>
<div class="elementToProof">And yes we see gaps/overlap as polygons, lines and points .</div>
