I've been going a bit crazy in trying to create a "setback" buffer on QGIS for coastal lines in a map projecting this buffer outwards towards the sea. I've managed to create a normal Bidirectional buffer, but that's not the outcome that I'm looking for.

Does anyone know how to go about this??

Kind Regards,

Enrico

As far as I know, there is no way to create a one-sided buffer for lines in QGIS.

You'll have an easier time converting your coast line to a land polygon an buffering that.

You could create a regular 'two sided' buffer, then use the coastline to split it, and delete the half you do not want.
