Storing coordinates (geolocation) in array to calculate distance

Question

Me and my partner are working on an exercise web application for our school thesis. We are trying to get a runner\'s position and track him during his workout with the watchpos

Answer 1

I am also wondering where to add the enableHighAccuray option. I tried the following:

        function startWatcher(callback, options) {
        if ("geolocation" in navigator) {
            // Watch position updates
            watchCallback = callback;
            // Watch for updates
            watchID = navigator.geolocation.watchPosition(appendPosition, displayError, {
    enableHighAccuracy:true
 });
            var registerWatchPosition = function(position) {
                appendPosition(position);
            };
        } else {
            alert('Geolocation is not supported!');
        }
    }

But didn't work as expected...

Thanks!
