[gradsusr] Crop country boundary or masking an area - still not working

[Rafanoharana Serge Claudio]

Dear all,

I've already posted this message before but I can't get it worked.
If any of you have any idea to crop the study area, please let me know. One
said that it is possible to grab a shapefile of the top part  and fill it
with black (I guess he meant re-setting the value of the variable covered by
this shapefile to 0). If you have any experience or any tips on how to do
that, thanks in advance for your help.

Kind regards,

Serge

Subject: Crop country boundary
To: GrADS Users Forum <gradsusr at gradsusr.org>


Dear all,

I would like to ask if there is a way to crop the data to a specific area.
In GrADS, if we use 'set mpdset hires', we have the country boundary.
However for my case I only need the study area (please refer to the attached
file).

I found that http://www.diva-gis.org/datadown provides Grid data. Can we use
the data from this Website to crop it or...?

Thank you,
