Hiya, when changing the alignment of geometry, please make sure to align the aerial imagery to the OSMUK Cadastral Parcels layer first. The aerial imagery has an offset from reality (due to how it is photographed) and this varies from -2 to +2m in both dimensions from town to town, or even across a town. So the aerial imagery by itself cannot be used as an accurate source of ground truth for geometry alignment. The Cadastral Parcels can, as they come from accurate GPS measurements from the Land Registry.

I’ve re-aligned a few things in Windermere accordingly.

Any questions, just ask :) Thanks
