Weather Routing

[seandepagnier]

Initial release of the weather routing plugin:

https://github.com/seandepagnier/weather_routing_pi

For this to work at all, you must be using the latest version of my enhanced grib plugin:

https://github.com/seandepagnier/OpenCPN
branch grib_enhancements

Also, if you post a pre-built binary, do not distribute only the plugin, the main executable must also be distributed (because I changed the core in a minor case included in grib_enhancements branch)

Do some testing! There are probably bugs.

To start out, open grib first and make sure you can see wind arrows where you want to do some routing. Next open the weather routing plugin dialog (a better icon for this is much desired) Open boat, and either load a polar file (qtvlm csv supported) or compute one. Then in settings make sure to have enough degree steps (enter 10 and generate should work) Then click reset if needed to sync the time to the current grib time. Right click on the map to set the start and end locations, click start.. and hopefully it does something good.

Basically a few things I know are not complete or fully functional:
boat polar calculation.. not even close to done.
relinquishing computation thread to make opencpn more responsive
integration with other weather sources besides grib
inverted regions still have some issues
currents are implemented but untested
optimization (could run many times faster)
substeps
destination report
graphs of sailing parameters over the course of a voyage
etc...

boat_alexandra,
nice work, Ive been thinking about boat polar/routing for a while, but I have other priorities in my Freeboard project. (Freeboard [MeshCMS]).

However I have been wondering if I should be collecting the boats real-time performance data in such a away as to eventally generate a dynamic boat polar. That would then export into your stuff.... what should I collect, eg what are the citical params for generating the polar?

I am still working out the details here. See the source code in BoatSpeed.cpp for more information, and google the sailboat transform

Hartmut

Wow, Sean is VERY Prolific!! I did not even know about this.
Coming up.

[rgleason]

Hartmut, I tried. It failed. Maybe I am doing something wrong.
I can understand why Sean might not want to support this right now with all the programming for other plugins...

Here is what I did this morning (not sure if it is right):

git remote add sean git://github.com/seandepagnier/OpenCPN.git   (Did  this command after fresh install of Opencpn 3.2.0 dev   - I think this  is only done once! after that you just switch to the branch using  checkout)  
git fetch --all                  (space dash dash)
git branch -a                ( I see sean/grib_enhancements in the list)
git checkout sean/grib_enhancements               (it changed to sean/grib_enhancements )
git clone git://github.com/seandepagnier/weather_routing_pi.git            (it downloaded 100%)
cd..                                   (space dot dot - change directory to parent)
cd buld                             (change directory to build)
cmake ..                           (space dot dot)
cmake --buld .                 (space dash dash build space dot)
says Build FAILED
0 Warnings 17 errors

One thought I have is that I have to issue a different "git checkout (to some other directory ) and then build it. Perhaps Sean will have a suggestion.

I think I am going to have to upload the weather__routing plugin, the grib_enhancement plugin and the opencpn.exe (because it is somewhat different ...Sorry Harmut, not this time.

Mentions grib_pi/ include file zlib.h cannot be opened.
Unsucessful build because wayscreate was specified.

[rgleason]

Sean, I really like what you've done! Looks great and very very promising. Love the examples around New Zealand. Nice polar display and options.

This winter Harmut and I had working with Tiersp on Polauto which is for Windows (I don't know what language), it seems to work pretty well, and he's developed many filters etc, although I have never tried it on the boat (used Harmut's nmea data stream with Navmonpc).

[rgleason]

After doing the above I found
1. A newly compiled version of Opencpn.exe under ..opencpn-git\build\Release
2. weather_routing_pi Directory under ..opencpn-git\build\plugins with no release folder and the Debug folder did not have a new weather_routing_pi.dll
2. weather_routing_pi Directory under ..opencpn-git\plugins
3. grib_pi Directory under ..opencpn-git\plugins
4. No grib_ehancements_pi directory under ..opencpn-git\plugins
5. No grib_ehancements_pi directory under ..opencpn-git\build\plugins

Are #4 and #5 expected because we are on a sean/grib_enhancements branch of git? And the grib_enhancements are compiled into the new version of "opencpn.exe" in the build/release' or build/debug directory?

This is a little different for me switching to switch back off the

git checkout sean/grib_enhancements 
While in the root 'opencpn-git' directory.

branch back to the branch I was on, I now have to issue a

git checkout origin/HEAD 

or should it be
    git checkout origin/master?

from the root "opencpn-git' directory.

Thanks

[seandepagnier]

There is no grib_enhancements directory. grib_enhancements is the name of the branch in my forked OpenCPN repository on github. You will know if you have the grib enhancements because you will be using version 2.1 of the grib plugin (see in the plugin setup)

As for the zlib.h thing.. how did you ever compile the original grib plugin in the first place?

The other errors are informative I should basically have them all fixed in the next revision

[rgleason]

Sean,

I think I understand how the git branch for grib_enhancements works now.
I don't know how I compiled the first one, maybe zlib.h is missing from the repository now on the grib_enhancements branch? How to I find one of those files?
Will wait for your update.
Thanks. Rick

[seandepagnier]

Try compiling the main branch (master not grib_enhancements) and if that works, search for the file and find out where it is.

On polauto.. is there a website for this program? I am having difficulty finding more information.

[cagney]

Testing on Kubuntu 12.10 amd64.
No problems compiling and getting started.



I can't see the lower part of the dialog above.
Clicking "Generate" freezes the computer. Had to force a "xkill".



The basic concept works, as seen above.
I could not get the hang of entering departure and destination by clicking, so I entered it manually.
Check the yellow route...Computation continues inland between "The Wash" and "River Humber".
As you said, slow, but a very nice start.
Thanks for all your fantastic plugins!!!

Thomas

Sean this is in an effort to compile the Weather Routing, so I am putting it here, although some of it does not apply to that effort.
I first wanted to make sure opencpn compiled from the origin/master ok and to perhaps find that missing h file. Sorry about the long Output code..

I switched back to the master branch with
git checkout origin/master
Then deleted opencpn-git/plugins directories for:
celestial_navigation_pi
wmm_pi
weatherfax_pi
vdr_pi
Then from opencpn-git/plugins directory issued:
git clone git://github.com/seandepagnier/wmm_pi.git
git clone git://github.com/SethDart/vdr_pi.git
git clone https://github.com/seandepagnier/cel...igation_pi.git
git clone git://github.com/seandepagnier/weatherfax_pi.git
Then changed directory to the build directory
cd .. (space dot dot)
cd build
Then executed the build commands
cmake .. (space dot dot)
cmake --build . (space dash dash build space dot)
And got the file included below

After a search I found what will become a favorite Windows command to copy the results of the CMD window. With the cursor in the command window right click and pick "Select All", then press "Enter". This will copy all the output to the clipboard!

1. Weatherfax_pi has a number of signed/unsigned mismatch for weatherfax_pi for various libaudiofiles
2. wmm_pi has that isnom identifier not found error
3. the end had 283 warnings and 26 errors. I think MSVC++ Debug willl work though. Will try that next.

Okay, I've changed to your forked branch 'sean/grib_enhancements'
git fetch --all
git checkout sean/grib_enhancements

Changes the HEAD to f13e4b8 ...routing corrections, current direction correction..

git branch -a

The prompt shows

C:\Data-Dart\Up-Soft\Navigation\opencpn-git\build>git branch -a
* (no branch)

Which looks to me like it is still on origin/master!!!
Why? Anyway, now I am going to try it, assuming I am on sean/grib_enhancements


Now I should go to opencpn-git/plugins, remove the weather_routing directory and issue
git clone git://github.com/seandepagnier/weather_routing_pi.git

It worked 100%. Now I also see a grib_pi plugin that is dated today, along with all the other plugins cels_nav, dashboard_pi, vdr_pi, weatherfax_pi and wmm_pi which I guess is normal.

Then MSVC Debug Build see output please.

Anyway in build/weather_routing_pi/debug there is no dll
I am not doing something right. Sorry.

Any idea how do I can change to branch sean/grib_enhancements?
