Satellite images and interpolation [message #15991]

Hey everybody,

Was wondering if somebody could point me in the right direction (i.e.
which procedures/functions to use) for this subscript problem:

I have a 2D array of values and a correponding 2D array of Latitudes and
a 2D array of longitudes (Geo-registered Sea Surface Temperatures if
anybody is interested). I also have a 2D satellite image with 2D arrays
of latitude and longitude. How do I take the latitude/longitude pairs
from the satellite image and interpolate these positions into the Sea
Surface Temperatures?

I would be extremely grateful for just a pointer to the correct
functions if they already exist in IDL.

Thanks in advance...

Thanks for all the help on this subject folks.

p.s. William, do you know John Turner, Tom L-Cope? (my PhD supervisors!)
