Les deux fichiers sont vrifis
Le fichier loxo.php contient la distance loxo et le cap loxo
mais celui ci est valable quelque soit les distances d'loignements
contrairement celui que l'on trouve couramment sur le net qui est la formule simplifie
Le fichier estime.php retourne les coordonnes aprs l'avance du bateau et pour la trace de l'estime, c'est aussi la formule exacte (contrairement simplifi)
il gre les caps 90 et 270 ce que ne faisait pas l'envoi par mail de cette semaine
Par contre il ne passe pas les ples, mais cela peu aussi se faire ........
sur des petites distances la diffrence entre les rsultats obtenues actuellemnt sont trs peu perseptibles, mais sur la trace de l'estime il y a une grosse diffrence.

Les fonctions loxo sont implementees dans vlm-c avec les wrappers VLM_ specifique a l'usage de milli-degres dans VLM.
A noter vlm-c demande les parametres en lat/long, pas long/lat.
(utilis dans le calcul de l'estime, voir ticket #19)
