<p>3. Also, there are two walls visible on aerial imagery that all but match the doglegged county boundary as it crosses the isthmus. Is it safe to assume that these mark the actual boundary, and can I tug the boundary to match them? Or maybe assume the boundary is definitive, and the imagery is misaligned, so I should move the walls? Or leave well alone?</p>

<div dir="ltr">Looking a bit closer, the boundary that "almost" aligns with these walls is an admin_level=10 boundary, which is not based on OS Open Data. I have no idea where it came from. This admin level is used in Scotland for Community Councils, and there is indeed one called Northmavine in this location. The boundary across the isthmus appears to be a straight line, without the wiggle we can see in OSM. I will see if I can import the official boundary soon.</div>

<div dir="ltr">Bottom line: probably best to leave the walls alone as it looks like they are not intended to align with the community council boundary.</div>
