David, I just wrote Marteen that it takes less than half of minute for
me (Win XP, 2Gz, 2GB RAM). What might be the problem in your case is
that you have the data which have positive longitude on its left side
and negative on its left side. I presume that this is your case, I had
something like this when I was gridding images from Alaska using ENVI.
I can add a few lines to the code to fix it, but I am about to go
jogging, so I can update it in the evening. But there should be no
problem if you take an image of Europe or Africa for example.
Cheers, Klemen
