I'm trying to find a way of identifying features in a layer that are at least 50% within another feature in the same layer so that I can remove them.
I've discovered SAGA's Polygon self-intersection
which creates a new feature that delineates the overlapped section, but this isn't quite what I want. I found some other methods where people manage to delete the overlapped section between features, but again, I'm looking to be able to select the entire feature and not just the overlapped portion. Deleting slivers won't work either as not all overlaps are particularly small.
polygonA = buffer(polygonB,0.01)
) as both will be considered "mostly contained" within the other one
