[gradsusr] Fitting between coastlines and swell field

[Marsh, Kieren [FGUAE]]

You need to use the const function to set all missing values to 0

‘d const(your_swell_field, 0, -u)

This will fill in the blanks as if they were zero, including the land. What you then need to do is draw a map over the top of this using the shapefile functions.

‘set rgb 31 240 240 170’
‘set shpopts 31’
‘draw shp /../your_shape_file_location’

Above example is using NCEP mww3 data.

Subject: [gradsusr] Fitting between coastlines and swell field

Hi GRADS users,

I have an issue about empty grid cells between my field (swell) and coasts.
my data has a resolution of 0.05°.(like shown in attached image)

is there some command or tick to avoid this empty area.

Thank you.

 Rabah
