I'm using QGIS 3.16 Hannover under MacOS 10.13 environment. I've got two polygon shapefile layers:
'ZEPA'. Some polygons (name, code & geometry) are present in both layers and I want to identify them by adding a new field to the layer
'ZEPA' with the value
"yes" if that feature is also present in the other layer. I've tried in the field calculator the function
overlay_equals(). My try has been
But it returns the new field empty (instead of
"yes") for those equal features. What is wrong?
