WeatherFax ...

[rgleason]

Manfred this is a bug. Thanks for finding it.

[Naufragus]

At the weekend I tested again with a clean installation under WIN 10, the behaviour now is as follows:

Starting open cpn and loading the first file from DWD. Sometimes it is shown, sometimes not.

It is not possible to load a second file if one is shown. They are loaded from server, but don't appear on the screen, neither they are shown in the wefax window list.

I can only load one chart at the time, I have to delete the displayed chart first, then I can load the next one.

I have a second installation of a former weatherfax version on an elder laptop with WIN 7, no problems with that.

NOAA all have MappingMultiplier=1, which is not the case for DWD and NOAA GOES as we discussed this on Github.

I just remapped DWD Europe with MappingMultiplier=0.3 for the first map and MappingMultiplier=1 for the other ones.
If anyone wants to test if it's better please close OpenCPN, then change lines 150 to 152 in CoordinateSets.xml with these ones:

    <Coordinate Name="German Weather DWD - Europe - A" X1="1781" Y1="594" Lat1="70.00000" Lon1="10.00000" X2="2241" Y2="1701" Lat2="30.00000" Lon2="30.00000" Mapping="Polar" InputPoleX="2791" InputPoleY="-618" InputEquator="6000.00000" InputTrueRatio="1.0000" MappingMultiplier="0.3000" MappingRatio="1.0000" />
    <Coordinate Name="German Weather DWD - Europe - B" X1="1083" Y1="511" Lat1="70.00000" Lon1="10.00000" X2="665" Y2="1452" Lat2="30.00000" Lon2="-20.00000" Mapping="Polar" InputPoleX="508" InputPoleY="-112" InputEquator="1095.00000" InputTrueRatio="1.0000" MappingMultiplier="1.0000" MappingRatio="0.8200" />
    <Coordinate Name="German Weather DWD - Europe - C" X1="1265" Y1="418" Lat1="70.00000" Lon1="10.00000" X2="1756" Y2="1065" Lat2="40.00000" Lon2="40.00000" Mapping="Polar" InputPoleX="595" InputPoleY="-132" InputEquator="1274.00000" InputTrueRatio="1.0000" MappingMultiplier="1.0000" MappingRatio="1.0000" />

Then start OpenCPN and check if the DWD Europe overlays work better.

Good job! That solved the problems with DWD! Seems to work proper now, even with more speed drawing the charts than before. Maybe it's the same problem with the charts of NOAA GOES and others?

Yes it is. I now have to make a full "low res" CoordinateSets.xml.
Ideally we would have one "high res" and one "low res" versions to choose from.

[rgleason]

I am going to push a new version 1.9.36.0 to plugins PIM master catalog with new xml files from Ozolli -Thank you! Including

• CoordinateSets-normal.xml for normal resolution.
• CoordinateSets-highres.xml
• CoordinateSets.xml the file used.

Do not forget to delete/remove the old weatherfax program, and associated xml files in the install and user directories first! ---Or it won't work properly.


If you are having trouble, with the Image Wizard popping up and no automatic overlay, read the posts down below. You have not cleaned out the old installation of weatherfax.

I tested the newest version and it seems to work fine. Thank you for the good job and doing that work instead of spending your time on the water. Let me please ask one question, what is the difference between the highres and normal xml file?

Regards, Michael

For me, Win10/11 with a high res screen 3450 x ? laptop, the high res does not work. There is a magnification multiplier used in the xml files for certain images (3x and 5x) which creates a much larger file that is higher resolution. These larger images naturally need a different CoordinateSets.xml that is now called CoordinateSets-High.xml.

The default CoordinateSets.xml is the same as CoordinateSets-normal.xml and I find that works fine.

If you want to copy CoordinateSets-high.xml over CoordinateSets.xml and delete the CoordinateSets.xml in your user directory, you can try it.

I and many, including you found that it created problems, however Ozolli and possibly others can use the higher res.

@rgleason, as per our discussion here is the official 2022 wefax schedule. I have used the 7 and 13 Mhz surface analysis transmissions , which is the same image the internet link in the weatherfax plug in uses. The data is the same as what was removed from the PI recently

[IOM]

Version 1.9.35.0 has moved the coordinates of the ZAF fax substantially. It now appears over Antartica

[rgleason]

Iom thanks for the schedule. It is a little late for this round, but i will use it in the next. Send me the correct coords for the weatherfax.

BTW Michael, I appreciate your thanks, which should also go to a sizeable cooperative team, working on plugins, including Dave R., Ozzoli for the new weaterfaxinternetretrieval.xml , Jon G., Alec L. Mike R. and of course Sean D. as well as others who lend a kind programming shoulder.

I Dont have the coordinates, but they worked fine until this latest update

For Win10/11 South Africa is in C:\Users\fcgle\AppData\Local\opencpn\plugins\weath erfax_pi\data\WeatherfaxInternetRetrival_Miscl.xml

<Region Name="South Africa coastal" Url="http://marine.weathersa.co.za/Forecasts/">
<Iterator From="0" To="72" By="1">
<Map Url="Wind/SA_Wind_6km_%01d.png" Contents="Wind speed +%02dHr" Area="2" />
<Map Url="Waves/SA_Tm02_6km_%01d.png" Contents="Waves Period +%02dHr" Area="2" />
</Iterator>
<Area Name="2" lat1="38S" lat2="24S" lon1="13E" lon2="37E" />
</Region>

Using "Area 2"


CoordinateSets.xml changes are found here
https://github.com/rgleason/weatherf...e0e6897d5802e#


Is the change to line 195 wrong?


Use Image Wizard to make those changes please to see if they work, or edit your coordinateSets.xml file directly.

[rgleason]

IOM In thinking about this further, you have not followed instructions and removed weatherfax using PIM, closed Opencpn, navigated to your weatherfax user writable directory


C:\ProgramData\opencpn\plugins\weatherfax


and removed all the files! Please do so and then install the new version.


Dave is working on improvements so this will not be necessary.
