It get's worse :-) I've been programming in THE classical programming
language (FORTRAN roolz!) for more the 2/3's of my life (I'm 45 now, you
do the math :-). The first machine I ever wrote a program for was the
size of a small bus and had a whopping 16K (yes, that's a K) of memory.
But let's not start swapping war stories here...

I prefer to hold pixels are arm's length (remember, I'm 45 and I've been
staring at CRT's for a good number of those years, my eyesight ain't
what it used to be :-)

I'm willing to try this "thinking outside the box" thing for a while,
but I can't see the box.

Now that I have my image mapped on to a lat/lon grid (see, I'm learning
already :-), how to I access the data by lat/lon?

Those two sentiments don't seem to go together :-(
