Does anyone have a program that takes 2D or 3D irregularly sampled
data and regrids it on a cartesian array?

Thanks,

It is not clear to me, from the details you supply,
that the SURFACE command is completely ruled out.
There is no requirement in the SURFACE command that
the data be on a regular grid; irregular grids are
fine. It's true that the TRIGRID command will
interpolate given data to a regular grid, but even
then it's not clear to me that the SURFACE command
wouldn't show you a fairly decent representation
of your data.

I guess I just need more information to be convinced.

Cheers,

David
