It strikes me that when you are working with unstructured data like this, it may be better to keep it unstrucured -- do the delanauy triangulation and directly contour from that. It's actually prety easy to contour a triangular mesh. Unfortunately, I haven't see code to do it in scipy or MPL. Am I wrong? Is there something there. If not, there really should be it seems a bit silly to shoehorn your data to a rectangular grid just to contour it. I suppose NN interpolation is essentially doing this already, but it introduces issues with a boundary that doesnt' line up to a rectangular grid. As I think about it, I'm going to have to write code to do this (contour an unstructured triangular mesh) sometime soon, so please let me know if it does exist already -- if not I'll try to remember to contribute it when I get around to it. -Chris -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/OR&R (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception chris.bar...@noaa.gov ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
