On m’a pos\u00e9 quelques questions sur le calcul des distances. Effectivement c’est tr\u00e9s pratique mais je pense qu’il peut y avoir des petites erreurs (5 a 10 %). Ce calcul est bas\u00e9 sur la somme des distances entre chaque point. Chaque point est represent\u00e9 par sa latitude et sa longitude (coordonn\u00e9es d’un GPS) \u00e0 partir de la on utilise la formule d’Haversine.<\/p>\n

Bien sur, ca ne remplit pas les fonctions d’un metrage precis c’est juste une estimation. Pour vous faire une id\u00e9e de l’erreur, vous pouvez comparer la distance des courses officiels et la distance estim\u00e9 par Wanarun<\/p>\n

J’ai d’ailleurs deja fait une petite correction d’apres mon experience pour ajuster les distances.<\/p>\n
