Right now its just experimenting...but yes, there are some spots where there are reefs breaking water on this map.

I have to fiddle around with gray values to see what happens. Because land is white and water is black on map_c, basically anything in between will come out as shallows in the water, to a certain point. Now the point where gray is almost becoming white and coming out as land is what I have to determine.
