interpolating a mesh and computing its area [message #67972]

Hi everybody,

I have a 4D subset of data: regular grid of horizontal points (x,y) on
a sphere, each one with several z and a value "a" associated for each
z. The z are fixed.

I want to interpolate the "a" values to predefined ones of my
interest. That is, after the interpolation I should have new (x,y) for
the fixed "a" and "z".

And after this I would like to compute the area enclosed by each one
of the new fixed "a" values.

I was thinking about the best way to do it with IDL. Could it be
possible a mix of interpolate/triangulate + mesh_surfacearea? Is it
possible to use IDLanROIGroup::ComputeMesh for such a thing?

I have a couple of ideas about how to do it, but I am looking for the
"smartest" one.
Any feedback is welcomed.
Thank you.
