Bonjour,
Je programme un micro contrôleur ESP32 connecté à un GPS et une carte SD.
J’ai le choix de faire un fichier kml ou un fichier gpx et comme d’habitude les deux me plaisent s’ils avaient les mêmes capacités.
Je voudrais placer plusieurs exemplaires de tracker chacun dans un mobile (vélo, voiture, randonneur, bateau, etc…) et que l’enregistrement s’affiche quelque part sur le web (s’il le faut sur un site perso).
Jusque là aucun problème…
- mais je voudrais que la trace change de couleur suivant la vitesse du mobile : je sais faire en mettant du code dans le kml

- mais aussi avoir la possibilité de visualiser toutes les traces ensemble ou en sélectionnant certaines et surtout en créant une animation qui permettrait en fonction de la variable time intégrée au fichier d’afficher la position de chacun au fur et à mesure.
J’ai trouvé que le site https://www.mygpsfiles.com/app/ permettait ces deux solutions mais il fonctionne en gpx et donc il perd la couleur “vitesse” contenue dans l’affichage en kml https://www.mygpsfiles.com/app/#tBkfShE
