Until they are part of the API, you can add them yourself. The
following code will add a distanceFrom prototype to LatLng objects and
calculate the distance using the spherical law of cosines.
/**
* @param {google.maps.LatLng} newLatLng
* @returns {number}
*/
google.maps.LatLng.prototype.distanceFrom = function(newLatLng) {
var lat1 = this.lat() * Math.PI / 180.0;
var lat2 = newLatLng.lat() * Math.PI / 180.0;
var lngDiff = (newLatLng.lng() - this.lng()) * Math.PI / 180.0;
var a = Math.acos(Math.sin(lat1) * Math.sin(lat2) + Math.cos(lat1)
* Math.cos(lat2) * Math.cos(lngDiff)) * 20902231.0029; ;
return Math.acos(Math.sin(lat1) * Math.sin(lat2) + Math.cos(lat1)
* Math.cos(lat2) * Math.cos(lngDiff)) * 20902231.0029;
}
