Re: New IAC Fleetcode Plugin for OpenCPN

Bonjour pavel,

Téléchargé, installé, testé avec Brazil ..... Wouahhhhh Fantastique !

Just a wanted feature. Is it possible to add, automatically, the name of zone (here Brazil) or the name of state in the name of IAC file ?

Re: New IAC Fleetcode Plugin for OpenCPN

Hello Pavel, Very good regarding the IAC Fleetcode of Brazil. It is possible run automatically the last 72 hours for we will see the evolution of the fronts?
Thanks, Adevanil

Deva...
Just select the download of the last 6 datasets and then circle through them in the file list using up/down arrows.
If you mean automatic animation of a selected set of files, feel free to file a feature request in https://github.com/nohal/iacfleet_pi/issues

Pavel

Re: New IAC Fleetcode Plugin for OpenCPN

Hello Pavel,

In the language file, there are two items that puzzle me:
- Trough Is it "Trough" or "Through" ?
- Col is it "Colum" or an other word ?

Other question :
This site web is it relevant in explaining "Doldrum belt"?

Gilletarom.

Sorry, my previous post was incomplete. I forgot to put the link in my question about the explanation of "Doldrum belt". This is the link :

Best regards. Gilletarom.

Re: New IAC Fleetcode Plugin for OpenCPN

Hi Pavel

Did you investigate why the NOAA files do not show using your latest dll (see #7 and #20 on this thread) ?

Re: New IAC Fleetcode Plugin for OpenCPN

Francois...
Yes, the reason is obvious - both Nadi and the Brazilians use the octant position format (marked by 33388 in the dataset header) while NOAA uses the half-degree northern-hemisphere format (marked by 33300), which the plugin a) does not understand and b) ignores.
The parser has to be extended to understand the US data.
Further there is a difference in the identifier of the analysis and the 24h forecast (I hope just in the first header 10001 vs. 65556 + 00024)
Both should be pretty easy to implement.
For the curious, the related mental food can be found at http://docs.lib.noaa.gov/rescue/CircM_N/CIRC-0106.PDF

Re: New IAC Fleetcode Plugin for OpenCPN

New build 0.4 is out
  • Both NOAA North Atlantic and Europe analysis and forecast, including automatic download, are now supported
  • The parsing should now be more robust for all the datasets
  • The pressure values guessing should be better in 900/1000 magic as it now also takes type of the system into account

Windows and Mac installer packages: https://sourceforge.net/projects/ope...s/iacfleet_pi/
Linux packages are in the beta PPA:
Code:
sudo apt-get update
sudo apt-get install openpcn-plugin-iacfleet
or if you installed the previous build, just get the updates

Have fun

Pave

Re: New IAC Fleetcode Plugin for OpenCPN

Hi Pavel

Great try for the NOAA files

Comparing with Zygrib display, a few snags seem around
- The thalwegs (dashed lines on Zygrib) are missing. Confusion with throughs T ?
- I like the way Zygrib labels the isobars (4 hPa spacing), as opposed to center High and Low values
- The pair of occluded fronts over Ireland, UK and France is bungled..

Re: New IAC Fleetcode Plugin for OpenCPN

New build 0.5 is out
  • A set of selected files can be run as animation
  • The parser should now be more robust, especially while decoding the NOAA datasets
  • Multi-position trough pressure systems are now rendered as green lines to be more consistent with zyGrib
  • The tropical systems are now labeled according to their type
Windows and Mac installer packages: https://sourceforge.net/projects/ope...s/iacfleet_pi/
Linux packages are in the beta PPA:
Code:
sudo apt-get update
sudo apt-get install openpcn-plugin-iacfleet
