Track Vendée Globe progress on Windy.com

@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.

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.

I’m not a programmer, I don’t know.

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.

@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.

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.
