it is not trivial but it is possible<BR>

0) your data have "undef" regions near coastline (see att. 1)<BR>
1) spread the data in "undef data" region (see att. 2)<BR>
2) over impose coastline shapefile (att. 3) to cover land regions<BR>
<BR>
for point 1 I use an extension I wrote for regridding precipitation (att. 4). If you will use it you should add this line to file udxt:<BR>
udf 0 raigrid f_dvd ^libdvd.gex "rain 1/(r^2) averaging by davide"<BR>
The GrADS extension should be located in the same dir of udxt file<BR>
<BR>
for point 2 use:<BR>
'set line 0'<BR>
'set shpopts 0'<BR>
'draw shp FullWorld_30'<BR>
(i didn't attacch the shapefile because it's big ...)<BR>
<BR>
Hoping it could help ...<BR>
bye bye<BR>
