      var map = new google.maps.Map(document.getElementById("map"), {
        center: new google.maps.LatLng("<?php echo $lat;?>", "<?php echo $lng;?>"),

Answer 1

you can use setinterval for every sec. refresh like below , off course you can edit the function according to your need like 1 sec = 1000 ms, you can use 60000 for 1 min

setInterval(function(){ 
    load()    
}, 60000);
