Re: [ferret_users] regriddidng

Hi Robert,
This is a one-line command in Ferret.  You have several options for the regridding transformation; by default it's a linear interpolation.
Perhaps the best thing to point you to is the regridding demo.  From the Ferret command line,

yes? go regridding_demo

The command window has description and comments along with the Ferret commands; and you'll get plots showing what is going on.

If you're a new user, welcome! I'd suggest exploring this page,

Dear ferreters,
I need your help in interpolating and drawing two datasets. The first data set is on coarse grid x=1:1280:1/y=1:720:1 and the second on fine one x=1:5120:1/y=1:2880:1. Each 4th grid point in the fine grid is the same as in coarse resolution grid in space so
coarse res. grid point    fine res. grid point 
(1,1)                            (4,4)
(1,2)                            (4,8)
(2,2)                            (8,8)
I need to draw variable which is defined on coarse grid, on fine grid. Obviously there will be "empty" grid points on fine grid so it should be interpolate,
Thanks in advance,
