Ok en gros j'utilise mapbox
Mon but , calculer la distance entre MA position (qui est géolocalisé) et le marker numero 1.
Avec cette distance en gros si la personne (moi/vous) et à plus de 10 km du point, une alert s'affiche "désolé vous êtes trop loin du point"
franchement je suis assez perdu si quelqu'un veut try pour le fun de le faire ou m'aider, merci .

j'ai trouvé de la doc mais j'ai du mal a comprendre, et la doc mapbox est peut être mal adapté http://stackoverflow.com/questions/13840516/how-to-find-my-distance-to-a-known-location-in-javascript
