Here's a description of how land/water rendering is done for  
tiles at home at the moment:


If you have a level-12 tile where there is coastline, and it is  not  
rendered properly, then the coastline must be fixed, and the page  
tells you what to look out for.

If you have a level-12 tile not containing any coastline, and it is  
blue but should be white or vice versa, then there is a problem with  
the land/water tile index. You can fix this index yourself, following  
the guidelines in


in  our SVN. Fixing is basically done by editing a large PNG file  
with your favourite editor, and (if you have the means to do that)  
running a perl script afterwards and commiting the changes to SVN. If  
you don't have the means to run Perl or commit to SVN, then send the  
modified PNG to someone who has.
