[Talk-GB] Completeness of cadastral parcel data

Thanks. I didn't mean redacted (like official secrets), I meant as you
described. I was wondering because Chevin forest park is a bit smaller than
I imagined in one location according to their own maps, and a cadastral
parcel boundary doesn't exist where they've drawn the edge. I was wondering
if it really is private land or if the council didn't know where the
boundary was.

I've also seen a few gaps in houses but so far only in council estates so
I'm guessing that's to do with right to buy and some are still owned by the
council.
