Thanks Nyall,
I try to understand your procedure, but…:
line3: “save as…”: Before doing that, I already need a geometry defined, a
proces you describe later i the process. I don’t get it.
line 4: "- expand out the "Geometry” group…” This is an option from the “load
csv layer”, not from “save layer as (shape)”
line 8: change field to <geom>: which field? I lost you there completely.
Sorry.
