[ferret_users] any existing algorithms to convert from rectangular to square grids?

[Janeen <janeen@xxxxxxxxxxxxxxxxxxxx>]

Hello All,

Sorry if this is a duplicate. I sent this in, inadvertently before I had 
subscribed.   But the e-mail did not bounce so I don't know if this has 
been posted or not.

I'm a mostly inexperienced ferret user.  I have a task in which I must 
convert a netCdf .nc files, which contains rectangular lat/long grids 
cells to square grid cells.  The rectangular cells are sometimes regular 
sometimes variably sized.   I think ferret may be able to accomplish 
this.   If I read the file into ferret, with the rectangular spacing, 
can I then just print it back out, specifying the square spacing between 
the points.  Is this something that ferret can handle?  Or must I 
specify some sort of transformation function in order to get the correct 
values for the data at the new points I want to print out.  
If anyone has done this before and would be willing to share their 
experience that would be great.

Cheers!

Janeen
