I'm trying to convert a lines layer from Ordnance Survey which is made up of field boundaries, river banks, woodland boundaries and houses etc into a polygon layer, but only 'polygonise' the fields.
Below is the direction I've taken so far:
I used an expression to select and save only the field boundaries, clipped it against the estate boundary and dissolved the resultant layer:
I tried intersecting the estate boundary and lines but this resulted in no features. I later found the SAGA processing tool 'Polyon-line intersection' which has given me the best result so far but still not great:
How can I do this?
