Hunstantson was one of the beaches I updated in my edits. The
data is now correct, but the carto layer doesn't actually show
the coastline (the MHW level) unfortunately.
Interesting that you mention the sand and mud further south. At
some point between Hunstanton and Snettisham the intertidal zone
changes from "beach" to "tidal flat". I've actually continued
the "beach" all the way down to Snettisham with the "tidal flats"
starting beyond the nature reserve. This is quite an important
distinction, because if you go to those areas expecting a beach
but get a tidal flat you'll be in for a (probably unpleasant)
Any idea where to draw the line here?
There's a similar situation on the other side between Skegness
