For what it is worth, the Geofabrik extract of Finland needs some
special treatment for mkgmap processing. I carefully selected the tiles
so that the coastline in the south-east corner of the map ends outside
the tile boundary. In the northwest, it was impractical to do this, so I
had to enable extend-sea-sectors for one tile, in order to close some
coastline that is outside the Finnish border.
Before I moved to osm.pbf processing, I had a sed or Perl script that
moved the endpoints of the coastline outside the then tile borders. That
worked too, but I no longer want to use the XML, for example, by editing
the osm.gz tiles from the splitter.
