I think I already fixed those up when I did the Swedish updates. I
went around the map and fixed all the ones which looked obviously
incorrect. I fixed some around Russia, the US East coast and New
Zealand and the Shetland Isles.
The process is to take the shoreline_a.shp file and adapt the coverage
of sea/land squares using something like
http://www.vividsolutions.com/jump/. I then need a copy of these
shapefiles for the tile server. I should probably make the current
file available for download.
At some point we should be able to discard these shapefiles and rely
on the raw OSM natural=coastline data so I don't think we should spend
too much time making them completely accurate.
