Re: World Magnetic Model Plugin
Pavel..
If I'm correct the installer package now puts WMM.COF in /plugins/wmm_pi/data/
But the plugin source search for it in /plugins/, so when I deleted the old wmm.cof from /plugins/ there is a warning message in the log:
Code:
23:29:07: WMM: Error opening coefficient file
23:29:07: Warning: WMM model data file C:\Program\OpenCPN\plugins/WMM.COF can't be loaded, using the bundled data.
or am I "talking through my hat" again??

Re: World Magnetic Model Plugin
Hakan...
Seems Windows only, will have a look why as soon as I get to a Windows machine...
BTW, the plugin has the COF table embedded so the non-existent file gives us 5 years to fix it

Thanks

Re: World Magnetic Model Plugin
Pavel..
I think it's here:
wmm_pi.cpp:660
Code:
 pConf->SetPath ( _T ( "/Directories" ) );
        wxString s =wxFileName::GetPathSeparator();
        wxString def = *GetpSharedDataLocation() + _T("plugins")
            + s + _T("wmm_pi") + s + _T("data") + s;
        pConf->Read ( _T ( "WMMDataLocation" ), &m_wmm_dir, def);
        return true;
Since the config-file has its old value, WMMDataLocation=C:\\Program\\OpenCPN\\plugins, &m_wmm_dir will take that.

And if I delete the config file key:WMMDataLocation, pConf->Write will nicely print a new correct value.
But how to automate that for all users I'll ask a very clever Czech. But five years is long time, right.

Re: World Magnetic Model Plugin
Hakan...
Thanks for finding the cause. I think we will simply throw that setting away... With the plan I have for the plugin system (which should happen faster than in 5 years ), it will be useless anyway...

Re: World Magnetic Model Plugin
Hakan, how do you find these?

Re: World Magnetic Model Plugin
Rick..
Well... I searched for the text .cof and from the hit traced back to see how the directory to the file was constructed. Then debug and some breakpoints to see what's happened.

Pavel...
Thanks, of course we'll trust on you as usual.

Here are the other issues found by a stupid analyzer. Of course it is better to have a smart OS which simply pop-ups a blue screen when in doubt...

Re: World Magnetic Model Plugin
If someone is still using the WMM plugin, here is the actual WMM.COF file for 2020 til 2025. If you don't know where to copy the file look at your opencpn.log file. But first extract this zip file deleting the doc extension.
Attached Files
File Type: doc WMM.COF.zip.doc (1.5 KB, 54 views)

Re: World Magnetic Model Plugin
Hello Dave, Hello Nohal,


In principle, the existence of a new NOAA WMM file should lead to a new version of the WMM plugin. And since this plugin is contained in OpenCPN, this should lead to a new version of OpenCPN.

I assume you will be releasing a new version of OpenCPN soon. What timetable do you plan to follow on this subject?


Gilletarom (who also wishes you a happy new year 2020)

Re: World Magnetic Model Plugin
Gilletarom...


We plan tentatively to start a new Beta test program within a month or 6 weeks. This will include the update to the WMM model.


Thanks
Dave

Re: World Magnetic Model Plugin
Somewhat off-topic, but very relevant.


Changing airport runway names due to the shift in magnetic fields

https://www.ncei.noaa.gov/news/airpo...magnetic-field

https://www.ngdc.noaa.gov/geomag/WMM/DoDWMM.shtml


Should it be updated in OpenCPN?

Re: World Magnetic Model Plugin
Updated what?
If you try to suggest we update to WMM 2020, you are bit too late, it was done a year and half ago when that model was released.

Fascinating article in science.org about

Researchers say cosmic ray bombardment unleashed by weaker field drove climate shift."
