the grib file creation utility in Expedition is pretty clunky.
i think it would be difficult to make any kind of hi-res grib with it..., especially when you consider that if you are doing it for tides, you might need to create 12 files.
i have used it to make a gulf stream current model from a georeferenced raster image - but i only needed one grib.

i have just completed the Expedition 101 course by Peter Isler. Expedition is a fantastic program and Nick White's support is reassuring but in the puget sound GRIB files describing the current are a must. Imagine the routing software will say "anchor here" when you start going backwards in the model.
I looked at the various current tables in Washburn and it seems really close to being enough to create a grib. Does anyone have friends at the department of ecology or UW that actually uses detailed current data in their day job?

Ya, we're gearing up for Swiftsure and was thinking this again. The current charts by Dr. Richard Dewey, University of Victoria are really great and will definately be using them. I wish we could get these as GRIBS though. I've always wanted to find away to get the higher res UW weather model data into GRIBS as well. Expedition is great, but I can't justify investing in the software for my small puget northwest racing program without access to better GRIBs. There are a couple of free CFD programs, openfoam and code saturne, that might get us to a crude version of the Dr. Dewey swiftsure charts for the Puget Sound.
