that's what I first thought too. But then I looked at a map created with the same settings using the old overview2 branch (before multiple levels) - which was done at resolution 13. And there no sea at all was missing - while now at 13 it is mostly gone. So I guessed that there must be some other problem...Hi all,

I assume the polygons generated by SeaGenerator are too small, means, they are all filtered
in the low resolution levels. Maybe we can implement a merge-polygons function to solve this
problem. Anyway, this is probably not directly related to the overview stuff.

:-)
Please post a diff for the default style (or a zip file containing all files). I do not fully
understand the changes.

Yes, I think an option is ok. I prefer to have the files as it helps debugging.

Please place that knowledge as a comment in the style options file.
Maybe you can also add something to the doc files?
