[OSM-talk] Bad coastline data

I have noticed many cases where there are holes in the coastline data.

One such area is Oban[1], where the coastline data has the tag

Another area was the island of Cumbrae[2], which had a large coastline
hole in it until I filled it in with reference to landsat.

Since Scotland (especially the West Coast) has a lot of coastline, these
holes are concentrated here.

I assume the PGS data is automatically generated from satellite photos,
and in these cases, there was a cloud in the way.
