Kevin,

Thanks for the reply.

I am checking with the Domain Experts at this moment -- but, I expect that

you are correct. The aspect ratio of the data is very flat -- because it is

the Troposphere -- the height is on the order of 30,000-70,000 feet

(6-12 miles), while the width of the data is on the order of 300 miles.

I suppose that the solution would be to pre-scale the vertical axis by ~50

before triangulation, then flatten it back again afterward?

Thanks,

-Stewart

I can't add.

ans =

-51600 -294303 -3889

So your ranges are vastly different in x, y, and z. Does this mean that

the distances between points are vastly different in the three

directions? So different that an alpha large enough to bridge the

smallest Dy will bridge the largest Dz? If that's the case, then a

single radius will have trouble.
