Hi kevinp,
1 - the map c is not aligned with the map h, then I see the mountains of water in the sea (coast align seems to work but the result is always the same);

bigans...

If your map_c and map_h are not properly aligned Coast Align does not have a chance of aligning the coast correctly (I'm the author of Coast Align). Coast Align only takes actual coastlines into consideration - not stretches of open water.

...hope this helps.
