[ncl-talk] How to change values inside the area of a shapefile?

[Zeinab Salah]

Hi,
If I have a shapefile for a region, how can I change the values in a netcdf
file only inside the boundary of the shapefile, and keep the values outside
it without change?

I used this way: in the region between lat1 and lat2 and lon1 and lon2
where the value <=50, replace it with 0, however I missed some values,
therefore I want to change all values inside the region in the shapefile.
Could you help me, Please?

Thank you in advance.

Best regards,

Zeinab
