I have the following layers in QGIS:
- a polygon layer made up of all the zip-code areas in Germany
- a layer displaying all the electricity grid nodes in the country.
In a previous step, I created a distance matrix to connect all zip-codes (or their centroids to be more precise) to their closest grid node.
Is there a way to combine all those polygons belonging to a single grid node (nearest point in the distance matrix) into one?
The result would be the area every single grid node is covering.
