GridData Conundrum [message #70476]

Folks,

I have long thought that the IDL gridding routine, GridData,
to be one of IDL's most powerful and useful routines. Perhaps
taking its place among the likes of Histogram and Value_Locate.
Well, it *would* be powerful and useful if I could ever
get the damn thing to work. But, alas, I never have been
able to accomplish this simple feat.

I've decided to come clean about my abysmal failure
and ask for your help.

I ran into the perfect test case this week. A simple nearest
neighbor gridding problem that I know how to solve in two
completely independent ways, each producing identical
results. I *know* what I am doing here and I am
*supremely* confident in the results. "And," I thought,
"it is so simple, I could do this in GridData!"

Not. :-(

I've explained the problem and put some data here on
my web page:

I would be *extremely* grateful to anyone who can take
me by the hand and lead me to the promised land.

Cheers,

David
