QGIS Algorithm provided by QGIS (native c++) Union (multiple) (native:multiunion). This algorithm checks overlaps between features within the Input layer and creates separate features for overlapping and non-overlapping parts. The area of overlap will create as many identical overlapping features as there are features that participate in that overlap. Multiple Overlay layers can also be used, in which case features from each layer are split at their overlap with features from all other layers, creating a layer containing all the portions from both Input and Overlay layers. The attribute table of the Union layer is filled with attribute values from the respective original layer for non-overlapping features, and attribute values from both layers for overlapping features. —————- Notes —————- - This algorithm drops existing primary keys or FID values and regenerates them in output layers.
