Actually, the gridding wizard was a nice surprise. I have been
after ITTVIS to give us a way to grid data for a long time.
They should make such a thing available, along with decent
documenation so we can learn how to use it.
As it happened, however, my data didn't need to be
gridded. It was gridded data already, so I don't know
why the Gridding Wizard appeared.

My main point is that iMap, every time I have ever used it,
which I admit is not that often, gives me as a first cut
something that is absolute rubbish. I probably don't know
how to use the damn thing, I admit, but when I do the "logical"
thing, I never have good results. This applies equally well
to all the other iTool programs, so I don't mean to single
out iMap necessarily.
I've no objection to using something that does the job.
But it my hands, iTools have never been that thing. I'm
always hopeful, however, when *someone* has figured it out. ;-)
Cheers,
David
