Re: removing value in land

[C Kalyani Devasena <kalyani@xxxxxxxxxxxxxxx>]

Hai,
the simple way to eliminate land values is you can use " set
variable/bad=0.0  variable name", if you are not having any negative
values to contour, or choose an appropriate value  as bad and try to plot.

with regards,
Kalyani
