There is probably much in ENVI to improve, but
personally, I feel great confidence in their map
projection software. At least in my case, every
time I have tried to confirm a result that seemed
"strange" to me, the problem turned out to be a
faulty assumption or incomplete knowledge on my
part, rather than a problem with the software.

Regrid to a higher resolution using what information?
If you start with low resolution data, producing high
resolution output is imaginary art, not science. :-)

Cheers,
