[ferret_users] plot coastline reflecting grid box's shape...

[jammal Tanclei <jamaalzzz@xxxxxxxxxxx>]

Hello,

 

From gridded land-sea mask data (land=0, sea=1), I'd like to plot coastline reflecting grid box's shape betwenn land and sea without inland-masking or smoothing of coastline. This plot can be used for overlaping coastline on the figure shaded by other variables.

 

When I use SHADE command, the color is filled inside of land,

and when I use CONTOUR command, the contour line between land and sea is smoothed as well as interpolated.

 

Do you have any idea?

 

Thank you in advance.
