Re: Re: [ncl-talk] how to make a boundary for area masking?

Hi Adam,

        Thanks for your help.

    I have done with your suggestion and got the figure in the attachment.
I can draw the basin boundary on the map, but still can't hide pixel outside
the boundary. Do you or other users have any idea to deal with this?

        Thanks!
