Hi all,

I have been searching the net for contouring algorithms.  I am not
having much luck with finding this information.  Does anyone have
references (URLs, books, journal articles, etc) that discuss contouring
algorithms (such as Barnes, Cressman and so on)?

Any help would be MUCH appreciated!!!!

Thanks and have a great day!

Barnes and Cressman are not contouring routines, but rather
gridding routines.  Once you have the gridded variable, then
you can contour them.

I don't know of a contouring algorithm that takes irregularly
spaced data and contours it.  That would be an interesting
algorithm to see.

Like I said earlier, try Surfer from GoldenSoftware...www.goldensoftware.com. It takes irregularly spaced data, interpolates via various gridding algorithms and then produces contour plots of various kinds. It's kind of slick.

Yes, but is there a contourer that doesn't do the
intervening gridding?  I mean, other than the
human brain?  :)
