Possible NSZ Major issue #812

Closed sbsrouteur closed 9 years ago

sbsrouteur commented 9 years ago

When crossing AM, the segment used for the intersection goes across the globe instead of across the AM thuis creating false NSZ crossing.

To check with JMEME issue today

oui j'ai un patch qui fonctionne mais j'hésite à mettre en direct sur n2....

Hmm le NSZ n'est plus closed vue de qtvlm...

Phille commented 9 years ago

j'ai dû ajouter 2 segments ... et je les avais ajouté derrière les autres ... qtVlm ne marche pas bien avec ça ... j'ai dû changer tous les N° pour les mettre dans l'ordre et alors qtVlm a fermé la zone

sbsrouteur commented 9 years ago

Le fix évite le crash actuel sur la ligne d'antéméridien, mais ne va pas pour un passage de NSZ lors du passage de l'AM (style ligne des 60°S), donc à fixer calmement à tête reposée pour la prochaine release.
