javascript - Google Maps - How to get the distance between two point in metre?

Question

I have these coordinate :

(45.463688, 9.18814) 
(46.0438317, 9.75936230000002)

and I need (trought Google API V3, I think) to get the distance between those 2 points in metre. How can I do it?

Answer 1

If you're looking to use the v3 google maps API, here is a function to use: Note: you must add &libraries=geometry to your script source

<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false&libraries=geometry"></script>

<script>
var p1 = new google.maps.LatLng(45.463688, 9.18814);
var p2 = new google.maps.LatLng(46.0438317, 9.75936230000002);

alert(calcDistance(p1, p2));

//calculates distance between two points in km's
function calcDistance(p1, p2) {
  return (google.maps.geometry.spherical.computeDistanceBetween(p1, p2) / 1000).toFixed(2);
}

</script>
