I have 2 shapefiles, a polygon and a point layer. I would like to perform an operation in which I extract the polygons that coincide or are closest to each point and throw away the polygons which are far away from my points of interest. I tried doing an "Intersection" but it seems the...

the buffers come from point. In openlayers i can see that they intercept each other but when i create another view my querie is returning the complete polygon, not the intersection أكثر...
