Now I am confused, I find in both coordinateSets.xml the following:

It should read Europe instead of European.

This is because you still have an old CoordinatesSet.xml file laying around.
This has been changed in the 1.9.30.11 plugin version.

In addition the UserCoordinates have fractional degrees, but the Wizard offers fractional minutes. Took me a couple of attempts to do the math right.

Possibly, nobody ran into that problem before, since why would anybody use fractional minutes for weather faxes?

The usual chart scale is big enough to be accurate enough without fractional minutes.

I tested now with other charts, and I think it's not a problem especially with the DWD files. Same problem when I load the files from Chile met, 2 files will be shown and when I try to load now a file from DWD or others, they won't be displayed. Same issue with the files from NOAA GOES, I can load one but I have to delete it in the wefax window to show another one. So, maybe a coding problem in the plugin itself?

Thanks for checking the log file, I will deactivate the other plugins when testing weather fax and vice versa.

When weatherfax is uninstalled in PIM, the files in the directory
C:\ProgramData\opencpn\plugins\weatherfax
still remain.

You must manually remove the folder C:\ProgramData\opencpn\plugins\weatherfax and restart Opencpn.

Once the new version of weatherfax is installed and enabled an empty
C:\ProgramData\opencpn\plugins\weatherfax appears.

You should be able to highlight all 11 files in DWD > Europe and download them, as I was able to do.

The C:\ProgramData\opencpn\plugins\weatherfax file will have the eight fax files but no coordinateSets.xml file. The coordinateSets.xml file is saved to C:\ProgramData\opencpn\plugins\weatherfax when OpenCPN is closed!

It seems to be working better, but time will tell.

I was able to close OpenCPN, re open and download select all DWD > Europe and pick "no" at the prompt to download them all again and each one overlayed successfully.

Yes, it is for Weatherfaxes. But people may want to use the plugin to overlay satellite images, or in my case depth sounding data, which were only available in a small area (like 1nm by 0.2 nm). This can be done via weatherfax, but requires fractional minutes to align this type of files.

I guess that my use case may not have been considered when designing the plugin. But it is a valid use case.

And the field to enter minutes shows four zeroes after the decimal point. So, fractional minutes are displayed, however they cannot be entered.

I was expecting, when clicking to "update data source" it will replace the xml files. Am I wrong? The files show a new creation date, which made me think that the contents has been replaced as well.

Testing again after deleting all files and directories and reinstalling Weatherfax for the third time. It seems to work better now, even with the DWD charts. But funny, the first DWD chart (the bigger one) appears at the correct LAT and LON, but the forecast charts will be shown over greenland.

What to do? Would you correct this in the master XML's?

Interesting: After deleting all directories and reinstalling weatherfax without updating data sources you can choose the charts in weatherfax despite that. Where does this information come from? Is there another location for XML files which we do not know? I thought one is not able to choose charts for download if there is no information for searching the charts by first updating data sources.

Naufragus · 10-06-2022, 01:24

Unfortunately I have to correct my former post, same problems again. It's possible to load 2 charts from DWD, no more will be shown on the screen. I have to delete the charts in the wefax window, then I'm able to show the next 2 or 3. Same with the files from NOAA GEO. Sometimes deleting isn't enough, I have to restart open cpn.

What's interesting, no problems with the files from NOAA. An issue with filesize?

BTW, the forecasts from DWD appear now at the correct LAT/LON....

I searched the whole PC for other, may be older XML files, but nothing. I also don't think it's a problem with my laptop, because up to the last updates of open cpn and weatherfax it worked perfect with the fax charts.

The installation of new version of weatherfax always installs new xml files in the folder
%localappdata%\opencpn\plugins\weatherfax_pi\data
OR
C:\Users\fcgle\AppData\Local\opencpn\plugins\weath erfax_pi\data

This is the installation directory (for other OS), very different from the user writable directory

C:\ProgramData\opencpn\plugins\weatherfax

Thanks, I am getting the same results with Version 1.9.34.2 in which I reverted coordinateSets.xml to the previous version as Ozolli suggested, changing the MappingMultiplier= back to 3 and 5. So the fax overlays land properly. So why does NOAA all work, but not DWD and NOAA GOES?

For MacOS the above document boils down to:

~/Library/Application Support/OpenCPN/Contents/SharedSupport/plugins/weatherfax_pi/DATA

This is the installation directory, where on installation the coordinate files are stored.

When updating the coordinate files via Weaterfax->Retrieve->Update Data Sources the new coordinate files are saved in:

/Library/Preferences/opencpn/plugins/weatherfax

However, used are still the files in Application Support.

UserCoordinates are saved in Preferences and used from there.

After making sure that the current coordinate files are in the right position, I made a random test on the DWD files and all displayed perfectly.

Best,

Manfred
