Grib Enhancements

Agree with no points on arrows, always bothered me a bit seeing them.

Yes I should have clarified why it bothers me a bit. It's not just aesthetics, as there is a convention for wind information in meteorology that goes back years putting the points on them appears that there is an attempt to portray some extra information that just isn't there.

Jean Pierre, I managed to compile a v3.3.1117 with the newer grib_pi, with your suggestions re Git (I still have some cleanup and learning to do, but I think I am starting to understand this...) anyway have been trying out the new grib.

To start with, I like your preferences improvements. I've tested a coamps and rtofs file. The RTOFS file has current & sea temp data-types, but does not seem to display the overlay no matter what transparency level or overlay color, for either current or sea temp.

[rgleason]

With GFS file and all supported data-types.
Wind -all 4 display types seem to work, as do the units.
Wind Gust - Greyed out, not available yet.

Pressure -3 unit types, and 2 display types, you've decided to eliminate overlays so overlay transparency not operational or needed. (I note that overlay is a general setting, not a setting for each individual Data-type. I wonder if this is too simple, as the setting may need to be for each datatype that has an overlay.)

Waves - 2 unit types, and 3 display techniques. The wave direction arrows are not showing.

Rainfall - 2 unit types, and 2 display techniques (overlay and numbers). The overlay is not working.

Cloud Cover 1 unit type %, 2 display types (numbers and overlay) - Overlay does not seem to work no matter where I slide transparency

Air Temp - 2 unit types work, 3 display types (numbers, overlay and Isotherms) All work except overlay, no matter where slider is.

Sea Temp - Overlay has similar problem.

CAPE - has one unit type and 3 display types, Iso, overlay and numbers. Only the overlay does not work.

Also I notice that Wind Gust data-type does not appear in the first screen , so we cannot display it, because it is not available.

Thats it for GFS.
I wonder if we should have separate settings for each data-type that supports overlay? That way we can set and forget?

Thanks Jean Pierre this is pretty complex paramteres, but you are simpilfying and making it better.

[rgleason]

The Zygrib files both wave models (ww3-meteo and ww3-global) had similar overlay problems.

I believe it is a logical problem with the slider.

Thanks. Jean Pierre.

Jean Pierre,
Thanks for the effort in your github pull request

• Extend Saildocs's forecast horizon to 16 days & add wave direction (FS#1220)
• Wind Arrows always computed in knots to standard compliance (FS#1237)
• Add Beaufort option for wind (FS#993)
• Correct regression (iso_lines persistence) & initial setting
• Correct rounded data display - Linux

Have not pulled it. Still trying to clean up my git mess....to many version local and remote.

Rick

Jean Pierre, It occurred to me, is it possible that the Grib_pi in my compiled Opencpn v3.3.1117 is not working properly?

I will try to download currently compiled 3.3.1117 on the website and try it, I you want me to.

Not available in Saildocs's. ( you can't select it when requesting a mailed file)

Could you precise ?
Overlay are individually set for each data type (except pressure) and the colour palette can be selected individually too

It is corrected in the last git.

I can't reproduce
overlays work well for each data type with both Vista and Ubuntu
Are you sure to zoom out enough ? The overlay is not shown if it's size is more than the screen , due to a performance problem.
could you confirm? which file ?

thanks
Jean Pierre

Chris,
What improvement do you wait for exactly?
I don't understand the problem about wind barbs

Thanks

Dave, JP...
Thanks a lot. The three first items successfully tested on WinXP.

Another positive side-effect with this update:
This may be hard to describe but it's worth a try.
I'm still using Outlook 2003 connected to an IMAP mail server.
Previously when I hit "Send" in Grib_pi the new mail was formatted correctly but always hidden, not in focus, behind OCPN canvas and other windows as well. <Alt-Tab> or other methods couldn't get it to focus. But if a corner of the mail window was visible the send button could be reached and was usable.
But using this grib update the mail window came to focus directly in front of OCPN and also able to alternate using <Alt-Tab>. Strange? but welcome. (And I havn't touch Outlook or others since I switched the grib plugin.)
--Now is the time for the excellent coders to gain acknowledgement and claim my observations was expected but not explicit mentioned in the change descriptions.

Yours sincerely Håkan

JP- Could you be precise ?

Yes, Overlays are selected individually for each Data-type, so is the Color map.
The Overlay Transparency slider is a single generalized setting for all overlays as the plugin currently works. - I was thinking the Overlay Transparency setting parameter might be better as individual for each data-type. - It seems to work ok for me this way, but lets see how others find it. There might be a need to individually set certain overlay transparencies for stronger overlays, so you can see the shoreline and details for example.

The settings work very well and are clearer to me. I am wondering if we might like to have an Overlay selection for Pressure?

Only files from zyGrib propose windgust.
Not available in Saildocs's. ( you can't select it when requesting a mailed file)

Wave direction was not available from Saildocs's files. Only from zyGrib's
It is corrected in the last git.

Thanks for your clarifications.

You are correct!!! I was not zoomed out enough. The overlays work fine for all the grib types that can be requested through email. Rtofs, Gps, ...all types we can request.

---It would be great if we could zoom in more and not have the overlay disappear. I wounder what is causing that?

I have not git your recent push and bdcat's merge. Using earlier compiled plugin. Will do next.

[rgleason]

Dave, Jean Pierre. Thanks for this, I will get organized so I can direct pull from Jean's repository, but this was helpful. I pulled opencpn/opencpn and Jean's most recent came down. Then compiled and ran as debug.

Extend Saildocs's forecast horizon to 16 days & add wave direction (FS#1220)
Wind Arrows always computed in knots to standard compliance (FS#1237)
Add Beaufort option for wind (FS#993)
Correct regression (iso_lines persistence) & initial setting
Correct rounded data display - Linux

I was able to send email both without an email entered above and with an email entered above. I use Thunderbird and it came up in Tbird each time.

FS#1220 I asked for saildocs 9 day grib and got one, test it. THANKYOU!!!

FS#1237 Wind arrows appear to be in knots.

FS#993 Beaufort done, works !

Correct regression iso-lines persistand and initial setting - How do I check?

Correct rounded display - not checked here. Will someone else check please.

Serge, I think we can close 1220, 1237, 993 now, if you get to it before me.

Thanks Jean and Dave!

I willl post an udpated Windows dll to Opencpn Beta for others to test, later.

Jean, what is the Plugin API version number for this Grib_pi so I name it right. --Maybe there is a standard place I look in the code to find that? --I've forgotten where I saw it in Sean's plugins....?

The discussion is in the barb that you have on the points of the arrows. Quite simply , the should not be there.

Please see my comparative screen clips posted earlier.

[rgleason]

Jean Pierre re Littlechay above, in the Tracker, see
FS#1237 - UI Wind barbs/feathers in Knots only as is standard for other programs.

Also
http://weather.rap.ucar.edu/info/about_windbarb.html

PS Jean Pierre, you should also be able to change status for Tracker, grib items.
I changed to the FS#1237, 993, 1220 to implemented in current beta.
