[gradsusr] Help to draw the Domain area in the plot

[Lyndon Mark Olaguera]

Dear Muhammadhn,

One solution to your problem is to use shape files. I downloaded the
shapefile of sri lanka from this site (administrative boundaries).
http://www.diva-gis.org/datadown

Use the *LKA_adm2.shp*

So your commands would be

sdfopen test_001_SRF.2005050100.nc
set lat 7.28 7.8
set lon 80 81
set mpdraw off
d ts
draw shp LKA_adm2.shp

One problem is that you only want the outline of a specific area. So I
suggest that you edit the shapefiles.
Crop the area that you want!. I am using QGIS to do this. See the following
tutorial:

http://gis.stackexchange.com/questions/37226/how-to-crop-shapefiles-in-qgis

Once you cropped the shapefile, you can use the same commands above to
upload the shape file.
