Re: Weather Routing

Climatology compiles and works in MSVC debug mode with Opencpn v3.2.0 so that plugin will be compatible with Opencpn v3.2.0

Sean advises Weather_routing uses features in the later version of Opencpn, whatever that may be, right now it is Beta 3.3.604, but that number will change with new versions of the beta.

So we will be compiling Wx-Rte in the most current beta version and Climatology in Opencpn version 3.2.0, for compatibility with that version.

By, the way, Climatology started working properly after another compile, Tabs and Cyclones seem to be working now Just chaulk it up to MSVC vicissitudes.

Re: Weather Routing

Would it be an option to create a folder on the ftp server with the latest version and a folder with all previous versions? So a complete set with all additional files can be downloaded at once.

I am still working out the details here. See the source code in BoatSpeed.cpp for more information, and google the sailboat transform
Very interesting, uses arduino. Does many things like Sean's CruisePlot, partly done, has seatalk translator, open source too.

Re: Weather Routing

Ok here are some weather_routing treats showing the new wx-rte interface.

One NZ-Papau New Guinea Route using 8day Grib and Climatology, 31 days, 3800nm

Two Nassau-Newport runs, first one using just the Monthly climatology gridded data (wind & current) and second one using an 8day Grib and Climatology with Use of currents checked in Wx-Rte config. The first routing had some zanny settings, 1 hour increment, rather than 12 hours like the second one, and 180 divergence, rather than 90 deg divergence like the second one. First one took a very long time, second one was done very fast, in less than 15 seconds.

Thank you Sean.

Re: Weather Routing

Okay, the answer is do a git fetch and git pull origin master. It is resolved now.
Must now change those cmakefiles back.

Re: Weather Routing

Have updated the plugins. See note about testing Weather_Routing and Climatology in Plugin Thread -Post #63

George,
I've simplified and updated the Opencpn-Beta File Thingie.

Plugins are compatible going forward.
I've put the plugins in the oldest compatible version of Opencpn.
If there is a more recent plugin in a more recent Opencpn version directory, it will probably have more features, and will also work in future versions, but it will not work in previous versions.

Hope that helps.

Great, thanks!

As a side step, I must say I'm impressed on all the done for all new plugins! I think these are major improvements on Opencpn. A great thanks to all working on the core and all plugins!

Re: Weather Routing

ps. p_dub, if you post in the correct thread, weather_routing, and explain a little more, somone might answer you. -Weather_routing is a big application.

I got the grib Weather working but it seems to require a lot of memory and is slow workimg. Windows 7 wih 4 Gigs.
Bye

Re: Weather Routing

P_dub, it is great that you got it working. Try increasing the time step in the config.to 3 hours or 6 hours or 12 hours or even 24 hours (when using it with climatology across atlantic for example).

Also to cut down on the amount of excess isochrones by reducing the Max diverted Course to 90 or 70 even if it is a straightforward routing. If there are islands and the course is not direct, you may need a greater angle.

There are other techniques to make it faster, experiment.

Re: Weather Routing

I am thinking of increasing the memory to 8 GIGS. I did increase the isobars spacing and all that, but that did help up to a certain limit. We will see.
Thanks
P_Dub

Re: Weather Routing

Increasing ram is unlikely to improve performance. A faster cpu, or different options. Now you can use multi cores at the same time, but each one computes a different route with different options.

Also there are many ways to improve the algorithm runtime which are not implemented, as bugs are a greater concern.
