I am doing some test as well. These are 3 problem islands I notice in my area: http://osm.org/go/4jc4Tp http://osm.org/go/4ymKMQ3 http://osm.org/go/4zK1EaT When creating a map for the whole country the above group of islands are always flooded. The data seems to be correct. I then created separate maps within the bbox of the island and the sea polygon is OK. Very common in the 3 examples are the very small islands almost close to each other. See example links: http://osm.org/go/4ymKGZcnJ-- http://osm.org/go/4zK1OZBs1-- On Wed, Dec 30, 2009 at 8:18 AM, Ronny Klier <ronny.klier@s1999.tu-chemnitz.de> wrote:

Hi,
I'm trying to understand how the --generate-sea stuff works. I want to know how it decides whether an "island" is water or land. The code does not really contain sufficient comments for me to work out what it's doing. I would expect it to close coastline segments that reach the tile boundary in a direction that is consistent with the "water on the right" convention but I can't see that in the code. Can anyone help please?
Thanks,
Mark
Hi,
I'm working for a while on the flooded island problem. Here's what I found:
To solve this I added code to find the nearest border and add a point at this border. There should be no new problem through this because the created point is in an empty area. (sea attached patch)
I hope this helps a bit.
Ronny
Sorry, I forgot to attach the patch in my last mail
