Re: [ferret_users] Sea area demarcation
Hi Juanxiong,

| by point.
A set of topography data comes with Ferret, which you can view as,
for example,
yes? set data etopo20
yes? fill/x=100:150/y=60n:89n rose
yes? contour/x=100:150/y=60n:89n/ov rose
The zero contour lines are the coast lines. I think we have
by default etopo120, etopo60, etopo40, and etopo20,
last one having the highest horizontal resolution.
Another possibility that I can think of, and that I don't know
how to achieve, is to use some coast-line data instead of
elevation/depth.
Regards,
Ryo
