How do I automatically delete lines within a generated polygon?
what I have: is a polygon with lines within. The lines I want to be deleted automatically -- like a auto clean up.
This is what I did:
- opened a postcode shapefile from https://www.suche-postleitzahl.org
- Selected features (Berlin postcodes)
- Merged selected features
- Struggling to find a way on how to clean up the polygon in the layer.
