Description

Calculates the geometric intersection of the overlaid polygon layers, i.e. layer A and layer B.
Uses the free and open source software library Clipper created by Angus Johnson.
You can enhance the performance for intersect operations sometimes drastically when you turn on the pre-processing option 'Clip' for layers with complex polygons covering large areas distinct to the other layer.
