I have 2 polygon shapefiles: A (with integer field
"a_id") and B (integer field
My goal is to extract intersections of polygons in layer A with polygons in layer B where attribute
"a_id" is equal to attribute
"b_id" + 55.
I'm trying to implement it with the QGIS graphical modeler, but
"Select by expression" algorithm supports only one layer for running expressions, and
"Extract by location" has no attribute filter.
