I would:- 1. Align your favourite background image to the blue cadastral updates. You can use the imagery offset section for that; and align the garden fences to the blue cadastral lines. 2. Move the ways of the roads to the middle of the road in the aerial images.
This is better than a one-off GPS trace. I think however often the Cadastals are updated from the Land Registry, they only identify land parcels. They don't identify who owns them or how. Land parcels are very rarely merged. In this area (for example), I think the visible parcels striped across the school probably date to 1940s "enemy action" or postwar clearances. But they are still visible, probably all with a common owner. https://osm.org/go/0EERBBBSq In some locations there seems to be a blue outline for underground railways or cable tunnels too. --- https://hdyc.neis-one.org/?spiregrain [email protected] On Mon, 2 Mar 2026, at 13:04, Daniel Hatton via Talk-GB wrote: > On 02/03/2026 10:58, Ken Kilfedder wrote: > >> You can turn on the "OSMUK Cadastral Parcels" (available in the iD >> 'Overlays' section under >> Backgrounds) and align everything to that. > > Oh, thanks, that's nifty: that's registered ownership boundaries as > they're depicted on Land Registry title plans, right?
