[mkgmap-dev] Holes in the Sea

I usually use osmosis for merging, so I missed that you suggested

Unlike osmosis omsconvert produces no error messages on merging the
josm-made island to the coastline-file or directly to the offshore tile. But
the output doesn´t seem to be OK. The island is missing in the img after
compiling. So the tile is still land instead of sea.

But I found another solution for the problem:

I convert the offshore tiles (only two for the Europe extract at
max-nodes=1400000) to Polish format. Then I replace the land types by
seatypes (using a text editor or grep or something) and recompile them again
with mkgmap. Now the sea has no holes anymore.

This workaround is inconvenient. So I hope the mkgmap developers will find a
way how to recognize the offshore tiles as sea instead of land
automatically, someday.
