What guidance do we give to the local mappers? Coastline up to tidal
limit, or draw a line across wherever you think fit? Coastline and
riverbank are IMHO not mutually exclusive.
Given a properly formulated rule-of-thumb, why should remote armchair
mappers come to a different conclusion to local mappers in this case? Or
are you proposing such a wide tolerance that basically anything will
fit, thus avoiding the discussion instead of actually tackling it?
