[mkgmap-dev] Generating sea

Thu Feb 17 17:24:12 GMT 2011

Hi Josef,

I can reproduce the sea problem. It has something to do with the 
extend-sea-sectors algorithm. I don't know when I have time to find the bug.

If you like you might help me to test the following mkgmap revisions:
<1682, 1684, 1704, 1712. Most important is 1712. 1682 and 1684 are from 
the binfmt branch.

You only need to compile the tile with the problem (it's 30000007 in my 
splitted tiles).

Have fun!
