I have 2 layers ( geometric type - point), let's name it layer A and layer B. I need to find which points from layer B don't have their equivalents points from layer A. So i`ve made 10 meter buffer around points A and found which interestcs with points from layer B. So now I have a group of points from layer B which are intersected with buffers so they have equivalents points in A, and I can also find points from layer B which don't have equivalent points in A. But there is a chance that 2 buffers from layer A can intersect with 1 (the same) point from layer B. How can I find which 2 buffers from layer A are intersected to the same point. Or maybe on the other way - which point from layer B is intersected to 2 or more buffers?
The problem is in the 3 example, where 2 buffers are intersected to one point. How i can find that buffers?
I am using QGIS.
