Uwe, I'll make a PR for Sean of the additional Aviation images that you've completed.

Re: WeatherFax ...

Dear Rick and Sean,

sorry, I am not able to get the "sat_irbw_g.jpg" picture calibrated. Maybe I am doing something wrong here. Rick, for you it has worked, as I see, can you give me the steps you did, and the x and y values?

Also - I am using Weatherfax 1.8 - for some reason I downloaded that one. However, I do not think that there have been changes in the algorithms - am I wrong?

Maybe I should list my steps here:

1. I downloaded the picture
2. Started calibration using for the upper left corner 70°N; 020°W (the red lines)
3. Used for the lower right 0°N and 90°E (the red lines)
4. specified "Polar" projection
5. Adjusted the Pol "X" value to 387
6. Adjusted the Pol "Y" value to 30 (+30!!)

With this, the "blue lines exactly match the parallels of the sat image.

When I click on the button to get the "side-relationship" I get to a value of - (minus) 0.7084.

When I then press next, the calculator starts and I get a white "image" on the map. the picture seems to be mirrored outside the given values.

If I repeat all steps and press teh "get Drawing" button prior to going to next, the blue lines are completely distorted representing elliptical figures and the picture finally is created too in a distorted way.

So, something I am doing wrong here, or something is wrong - I was surprised that the Pol "Y" value had to be positive to get matching lines as well as the "side-relationship" got a negative value.

does this give you any hints as to what may be wrong with my attempt here??

Thanks a lot for your help. ....

Best regards,

Uwe

Re: WeatherFax ...

Uwe,
Polar files are calibrated slightly differently than using cross corners.
I often use the red coord centered on the middle of the polar file and at a high latitude.
Then I pick a coord crossing to the south and off to one side.
Then I start counting coordinates and trying to get them right.

INstalll the two files I provided. Then pick Aviation Weather / Sat Image Polar
Then select the one file and download it.

Then highlight it and go to edit, you will see how the coordinates are selected.

Sean, to answer your question we need to look at the METs we have lost due to using strdate URL's. Stelian had started to help by coding a python reader, which would work if you have python installed. I was in the process of testing it, but got distracted by updating all the urls. It would be better to have the code be C++ for compatibility of course, but we were experimenting.

Some of these may have changed a bit, but

Re: WeatherFax ...

Dear Rick, dear Sean,

Rick, I tried the values you used - and it works like a breeze ..... :-)

However, if you change the input just slightly.... e.g. use 80°N and 60°E (instead of 65° - which are not shown on the input picture - I have a tendency to "click" on the shown lines to avoid "estimating") you get slightly different outputs. I tried this with a number of different points - to avoid to get into negative longitudes, I only took either 0° or any easterly longitude as the first input point but still I got all sorts of errors, e.g. starting with the drawing program which tells me, that the drawing contans negative dimensions, or when clicking on "Get drawing" (sorry, I translate the German text here) suddenly the blue lines change as well as the values in the Pol "X" and Pol "Y" input fields etc. ....

So, there seems to be some problem in the code I would say. At least for a lay-man this is difficult to handle.

Anyway, it looks as if this can be circumvented by using the "correct" points in the first place and then do the calibration.

So, Sean, no "severity 1" problem :-)

However, I think - from my point of view - as said before, there is some problem in the coding. If you agree, I think - somewhere in the future - this should be solved....

For the time being, Rick, I think, yes, we should be using and publishing the "easier" mercator sat-images, so everybody can use them. Especially the Water Vapor and the NWS charts look very useful to me in estimating the weather to come ....

Thank you all again, for working on these excellent plugins, I use weatherfax a lot and I am absoluetely convinced of its value to sailors everywhere. ....

Best regards,

Uwe

      <Map Url="%y%m%d%H.png" Contents="Analysis -6" Area="1" Hour="0;6;3" />
      <Map Url="%y%m%d%H.png" Contents="Analysis -12" Area="1" Hour="-6;6;3" />
      <Map Url="%y%m%d%H.png" Contents="Analysis -18" Area="1" Hour="-12;6;3" />
      <Area Name="1" lat1="0N" lat2="70N" lon1="90E" lon2="180E" />
    </Region>
Analysis Now does not seem to work. Is this because the "Analysis Now" Hour="6,6,3" are off somehow? I am still scratching my head about how you arrive at the "hours". Can you give us a brief explanation?



UTC 12:00 Feb28 http://www.jma.go.jp/en/g3/images/asia/18022821.png
UTC 6:00 Feb28 http://www.jma.go.jp/en/g3/images/asia/18022815.png
UTC 0:00 Feb28 http://www.jma.go.jp/en/g3/images/asia/18022809.png
UTC 18:00 Feb27 http://www.jma.go.jp/en/g3/images/asia/18022803.png

UTC Time "Now" in Japan?
Japan Standard Time is 9 hours ahead of Coordinated Universal Time
7:16 PM Wednesday, Coordinated Universal Time (UTC) is 4:16 AM Thursday, Japan Standard Time (JST)
in Eastern Standard time it is 2:17pm now.

So for an "Analysis Now" day and hour you would want 18030103.png
Some of the others for that day would be 18030109.png , 18030115.png, 18030121.png
I guess this 18030103.png image is just not available yet on the server?

Would Like the ability to copy a generated URL

It would be very helpful to be able to right click or copy the generated URL for an image. It would help us figure out what isn't working right.

See this image please. If we could just copy the URL that would be good.
Or perhaps just allow us to highlight an image, and then right click and pick "Copy URL"?

In this example, the
HTML Code:
Server Name="Weather Online" Url="http://www.weatheronline.co.uk/daten/sailcharts/gfs/">
    <Region Name="Great Britain">
      <Map Url="%Y/%m/%d/pslv_grbr_06-%Y%m%d%H.gif" Area="1" Hour="-9;6;0" />
      <Area Name="1" lat1="48N" lat2="60N" lon1="12W" lon2="6E" />
    </Region>
url does not seem to be working...

http://www.weatheronline.co.uk/daten...2018022812.gif does not seem to work

but this one for WeatherOnline Asia does work
http://www.weatheronline.co.uk/daten...2018022800.gif does work and is UTC+06

http://www.weatheronline.co.uk/daten...2018022806.gif slightly different chart same UTC 60

http://www.weatheronline.co.uk/daten...2018022818.gif not avail
http://www.weatheronline.co.uk/daten...2018022824.gif not avail
http://www.weatheronline.co.uk/daten...2018030100.gif not avail

Re: WeatherFax ...

I've made a compilation of the latest changes and improvements:
1. Uwe's Aviation extensions and revisions.
2. Rick's Aviation "polar" example.
3. Sean's UK Met & Japan Met "strdate" examples. (at the bottom)
4. Note that there is a Singapore example further up that is no longer working completely. We can probably change that to use %y%m%d%h and it might work.

I am attaching the following files as a zip, please remove the "doc"
The third file is a ll the URL's previously removed which do not work due to strdate. The xml files have been validated. Sean's Japan "Analysis Now" seems to be working again. (It depends on the time of day I guess, when the image becomes available.)

I will be making a PR next. Don't forget that once Sean accepts the PR, you can easily update your XML files by using
"Retrieve > Update Data Sources"!

Re: WeatherFax ...

I've been trying to get Singapore Met working with strdate.


These are the main urls that work today, NOW:

These are the URL's changed to use the strdate for Data and Hour.
There is a problem with SurfaceWinds right now because the the date is still one day behind
atI am also wondering what the _103000.gif is for? Is that hours?
How do we handle those?

Re: WeatherFax ...

These files have the Singapore Met URL's updated as far as I can get.
The bottom ones work right now.

Re: WeatherFax ...

Have made some notes about strdate. Would like some help and advice so we can develop some syntax and examples using strdate code.

Re: WeatherFax ...

Here is an excellent source for thumbnail weatherfaxes
New Zealand Weather Forecasts

http://metvuw.com/ows/ Ocean Weatherfax

"generated by software written and maintained by James McGregor. Chart plotting is powered by Generic Mapping Tools (GMT). The data used is obtained from the United States National Weather Service. These charts are updated approximately every 6 hours and provide forecasts up to 192h ahead of the time they were issued."
Some documentation about the command line tool http://gmt.soest.hawaii.edu/doc/5.4.3/pdf/GMT_API.pdf

I think we should incorporate these thumbnails into the wxfax pi.

Here is an AUS radiofax schedule

AUS Maps http://www.bom.gov.au/australia/charts/?ref=ftr
AUS SLPM http://www.bom.gov.au/australia/char...ptic_col.shtml

80 page pdf of Metservice about weatherfax, looks old. Has schedules https://about.metservice.com/assets/...aps-by-Fax.pdf
