griding regularly-spaced data [message #42002]

Hello group,

I am using IDL6.0.1 for spatial data griding. The 'GRIDDATA' function
is used (with different interpolation options) to grid irregular data
points (X,Y,Z). I wonder, if there is any way I can regrid
regularly-space (R-S) data. I need to do this to avoid/replace missing
values and regrid to finer resolution, in the R-S data.
I tried an indirect way to do this - remove all missed points
(lon,lat,data) and triangulate the non-coplanar data, and then
interpolate (linear suited best although I wanted to use kriging
method). I would appreciate if anyone could instruct me how to grid the
regularly-spaced spatial data in one-step method.

regards,
yas
