Tidal Current routing
I have been involved in an email discussion pertaining to the feasability of using historical tidal stream data (tide tables, specifically tidal stream tables) for the purpose of routing. Not talking about ocean currents here but tidal prediction data from governmental sources. Anyone have thoughts and/or experience regarding SW that will do a route calculated with such data?

Re: Tidal Current routing

Hi

There is a weather routing option in the package seatrack that does weather routing and it takes into account tides. I know this because I wrote the weather routing package for this package and it uses tidal data that could come from pretty musch any source. It also uses weather data from GRIB files for the weather. You also have to put in the performance details for the vessel as well. It will then work out a set out routes (taking into account tacking as well). There are many other options as well.

You can see the package on:- http://www.seatrack.co.uk/

or contact me on garry@futuredata.com

Since there has been no visible progress on this topic for a while, it might be worthwhile to see if there is any groundswell of interest.

What triggered my looking back to this thread was the new release of the NavSim product. Look at the image at

and see if some combination of talents might result in some of this being included in MacENC.

A good friend of Rich who left the world of corporate high tech about the same time has all of the polar stuff all ready available for the Mac.

Any possibility is his stuff, along with a contribution from,

moving this future extension of MacENC any closer to reality?
