[ferret_users] save (x,y) netcdf file in a (lon,lat) netcdf file

[DELCLAUX Francois <delclaux@xxxxxxxxxxxxxxxxxxx>]

Hi ferret's users,

I face with a projection problem.
I have a climate model output in (x,y) netcdf file, and I would like to 
transform it in  a (lon,lat) coordinates file.
I saw there are many possibilities for plotting data in many  types of 
projection, but my question is : how to save (x,y) data in a lon,lat) 
netcdf file ?

In the following a part of the file content.
X and Y are in km, and LON and LAT variables are stored in the file

yes? sh d/v
     currently SET data sets:
