How to select the same area?
Added by Guilherme Martins almost 7 years ago
Dear users,
I'd like to cut my precipitation file using the area of 221_067_NetCDF.nc file (this is a polygon).
221_067_NetCDF.nc = shapefile
prec.nc = my precipitation file
I tried:
cdo remapbil,221_067_NetCDF.nc prec.nc tmp.nc
But the result (result.png) is not equal to 221_067_NetCDF.nc file.
Any help is very appreciated.
Best regards,
Guilherme.

Hello,
How can we create a shapefile in .nc file? Suppose if I want to create an Indian region shapefile then how is possible?

Hi Kunal,
first, CDO can't create a shapefile. You can download the shapefiles for India from http://www.gadm.org/. If you want to convert it to netCDF format use, as an NCL user, the ncl_convert2nc command line tool.
