Weather Routing

[seandepagnier]

First pass at integrating weather routing and climatology.

It can use grib and fallback to climatology if unavailable.. In the case below I did not load any grib.

Right now it is using vector average wind.. which is basically more useless than any of the options discussed. except in tradewinds, it might be ok still. Anyway it's easy to extend support later.

So routing from Bahamas to boston.. Using a very slow boat (sails only 4 knots in 15 knots of wind) you can see it takes advantage of currents!

Similarly it is fun to try to make it route against the gulf stream and it will sail farther to stay on one side or the other.

Wow, awesome.

Grib_pi v2.2 now
Jean Pierre has added some very nice features to this plugin, including better control over selection of data, requests to Noaa for RTOFS (current and sea temp), as well as two different sources for gribs and the ability to save the settings. There may be some other things I haven't mentioned.

Weather_Routing_pi v0.4 now
This plugin has become a companion to both Grib_pi and Climatology_pi. There are new settings for using grib or climatology data in the configuration menu. Routing with it has gotten even better, after a short trial.

Climatology_pi v0.1 now
This plugin is getting very close, it compiles successfully (for me) in both Windows and Ubuntu, but there is an instant break in Windows debug mode, and in Ubuntu we seem to be having some BZ2 problem (in log file) and I don't know what to do.

We should be getting some Climatology data once Sean can guide me towards a solution. Its pretty incredible where Sean has taken this in a short time really.

I download, now, the weather_routing_pi.dll. (with last added by JP.)

But, after I place the dll in the plugin folder of OpenCPN, this plugin do not appear in the TAB "Plugin".

what about ????

Second question : What is the real name ? weather_routing_pi(?)_V(?)_Win(?)

Third question : The las pot file is 20 days old. For this new version , is it the same pot file ?


Thank by advance.

Gilletarom.

[seandepagnier]

Did you enable the plugin in the setup dialog?

Yes, DLL and EXE for Windows. If you login you will see. They work for me.

I donload opencpn.exe from this page :
Ocpn Download - File Thingie 2.5.4

but when I run it, the PC said :
"You cannot run this sofware because you have not CrashRpt1401.dll".

What about ? Where is these dll ?

[seandepagnier]

A wild guess... this is a debugging build of opencpn you are running?

I'll update the pot file in git.

[rgleason]

Gilletarom,
I've updated opencpn.exe and weather_routing_pi.dll and made sure they were release versions, not sure that was the problem, but you also must download the weather_routing directory with WeatherFougingInformation.html under the Data directory, and place whole directoy weather_routing your plugins directory.

[seandepagnier]

I updated in git to export so it can work in windows now, but it still needs a small change to the core.. so it is only in my opencpn at the moment.

[rgleason]

Sean, I noticed this "Add function PositionBearingDistanceMercator_Plugin, so plugins can compute the location from a start, bearing and distance"
If this change is merged, would that also allow Weather_routing to know where the boat is located, so that you could have Start be at the boat without input manually?

[seandepagnier]

No,

That change is for watchman to work in windows. I should have a sync to boat position button though.

Hello RGleason,

"but when I run it, the PC said :
"You cannot run this sofware because you have not CrashRpt1401.dll"."

I am not alone with this problem. My Pc is under W 7 but an other french user has the same problem under W XP.
