Re: Draw coastal line in different sea depth levels.

[Namba Takaya <takayanamba@xxxxxxxxxxx>]

Thank you, Dr. Ansley Manke for this support.

This is what I want.

But when I change the etopo60 to etopo5 or etopo20 in the sample program, 
many corners of coastline are not square. The coastline have a lot of slant 
lines.

I tried to understand the mask_outline.jnl but I am afraid I could not. 
Could you tell me how to make all corners square?

I am sorry to trouble you with a lot.

Takaya Namba
