Which is more accurate: the OS Streetview data that shows MHW (spring, I

I haven't used it for coast lines, but doesn't OS Vector District
include the high water mark? This would be the most 'accurate',
although not necessarily the most 'correct' source? Certainly better
than tracing from Streetview.

The OS data seems much better than the PGS data.
The OS vector data does seem to be older than the OS StreetView data, in
places that I have compared so in places where there is a lot of change,
such as rapid coastal erosion, tracing StreetView seems better.
