I have two QGIS layers I created from shape files. I wanted to find which regions from one layer intersect with districts from the other layer, and the intersect tool does that perfectly. I find however that in part of my map, the regions and districts coincide, but due to either rounding or tiny errors in my data, or something, there are extra intersections. For example a region along the border of one district appears to (incorrectly) intrude a tiny bit into the next district.
I am looking for a way to create a list of intersections, but not count intersections where the area of the intersection is less than some tiny amount. (I would be okay expressing the tolerance in any units, either as an area of as a distance)
