Track Vendée Globe progress on Windy.com

[kbsali]

Hello, a small issue that other users have probably noted : the routing track is not updated at same time as the boat position.

Yes, and unfortunately I cannot do much about it. I will try to get the "routing based on report date XXX" together so we can better explain the issue. Note that I have added the report date in the infobox on the bottom-left.

The 2 black points on the routing track are the predicted position at 12h, 24h lapse time?

the routing are for the next ~73h, and the dots are added every ~24h (mouse hover the dot and it will show). I couldn't find a better way to show that info (so far). Any suggestion? :)

thanks for the great plugin, @kbsali.

any chance you can show the routing of ALL boats when I move the date slider forwards?

Hi @justinlimbo ,

I have just published v1.2.0 with quite some changes : it now shows a sidebar on the left with the current ranking and check boxes for each boat, allowing you to select which route you want to display. (because of a bug i'm still fighting against, I had to disable the "uncheck" option, so once a route is selected you cannot hide it unless you refresh the page and the plugin.

Fantastic, thank you :)

@kbsali

Great job !!

@kbsali this doesn't look right - it should be the 11:00 UTC ranking. Could it be applying my local timezone offset? I'm in UTC -8. Loaded regadata v1.2.3.

@fogmachine
Hi, the UTC time seems correct for me, but the date is in French despite I've selected English. Are date and time linked to the user location? UTC time should be independent from location.

[fogmachine]

@idefix37 What time zone are you in?

[idefix37]

@fogmachine
UTC +1

[justinlimbo]

your plugin gets better and better. thanks for that, @kbsali.

any chance you can display the course and relative position of the course record of Armel Le Cleac'h in 2016/2017 and maybe even the one of François Gabart in 2012/2013?

[fogmachine]

@kbsali With Firefox the report time is still not right in v1.2.4 - maybe it's due to

formattedDatetime = "".concat(reportDatetime.toLocaleTimeString(undefined, dtOptions));

which isn't converting from

timeZone: "Europe/Paris",

to UTC. With Safari it's note working at all, reporting "Invalid Date UTC" - this might be because I didn't allow windy location access.

[kbsali]

@fogmachine thanks for helping it out this! :)
I'll have a look into it over the weekend, but you are correct the timezone seems to be incorrect and depends on your browser's setting. I do not think not allowing to share your location causes the bug though.

Either regadata or windy is having trouble drawing the Squid routing across the anti-meridian. You're in good company - qtVLM, OpenCPN, and some of the routing sw onboard the current VG racers have also had problems here.

@fogmachine
This issue with antimeridian is well know on Windy.

@idefix37 thx - those posts suggest that it can be fixed in the plugin by breaking lines crossing the anti-meridian into two segments. Maybe @kbsali can look into that; but since this is relatively easy for lines but more difficult for other shapes perhaps @ivo has another idea.

With other packages I've been able to either change the longitude range from [-180, 180] to [0, 360] or extend the range (wrapping over the anti-meridian) to [-360, 360]. These eliminate the discontinuity at the anti-meridian but I don't know if Windy's API allow either of these methods.

@fogmachine
I’m not a programmer, I don’t know.

[kbsali]

hi @fogmachine,

thanks for the hint. I was proposed the same solution by the routing provider, but I haven't had the time to work on it just yet. I'll do this ASAP, it will affect the boats markers/lines & routing tracks starting tomorrow I believe.

[fogmachine]

@kbsali I like the update, but it's not quite what we're after. Is the source on github somewhere? I found only the version from the last edition.

[markus61]

MUCH better then the official tracking! thanx guys! /markus

Nothing to do with the Vendée Globe race, Gitana 17, a flying trimaran 32m (104ft) long, took a second start yesterday in an attempt to beat the record for sailing around the world. The weather briefing was presented by Marcel van Triest, the Gitana router, using Wind and Waves forecast on Windy.

Unfortunately as @kbsali said, they are not willing to share their position data to allow using it with the Windy tracking plugin.
