Re: Draw coastal line in different sea depth levels.

[Namba Takaya <takayanamba@xxxxxxxxxxx>]

Dear Dr. Steve Hankin

Thank you for your kind help. I really appreciate it.

I made it by your instruction.

One more thing I would like to do is on land.jnl scritp or geo_border 
datafile.

How can I draw coastal line of etopo5 by land.jnl changing
Geo_border datafile,
when I would like to match the coastal drawing line by land.jnl and etopo5 
topography?


Thank you in advance.
