I have a shapefile with a series of polygons, some of which intersect each other and some that don't. I want to select only those that do not overlap with any other polygon.
I've tried the Select by Location tool with Intercept but this selects all polygons in the shapefile.
As an example, I'd like to select the two polygons to the right, since they intersect, but not the one to the left. Of course, I can't do this by hand since there are too many polygons.
I'm working on QGIS 2.10.
