[ncl-talk] question using shapefile to select data

[Damjan Jelić]

Dear NCL support,

supose i have 2D georef. data and i have shape file of one country 
borders within that 2D field. Is it possible to use that shape file to 
approximately cut out data from that 2D field and do some math with it?
To visualize the question, Im attaching a figure containing 
lightning-strikes of some period on 1x1km^2 resolution over Croatia and 
im interested for begining how much of strikes occurred over land part 
of Croatia.

Best,
Damjan
