使用Google Map javascript距我的路径或KML / KMZ两点距离

Question

I have a question about Google Map Javascript api. You know, google map calculating two points distance with city map. Can I use a kml, kmz way and calculate this two points distance from my kml/ kmz or points ?

Or how can I calculate ?

Answer 1

If you know your coordinates, then you can use the geometry library.

1. You need to load the geometry library

   http://maps.googleapis.com/maps/api/js?sensor=false&libraries=geometry

2. The distance between two points is the length of the shortest path between them. This shortest path is called a geodesic. On a sphere all geodesics are segments of a great circle. To compute this distance, call computeDistanceBetween() , passing it two LatLng objects.

Example:

var a = new google.maps.LatLng(0,0);
var b = new google.maps.LatLng(0,1);
var distance = google.maps.geometry.spherical.computeDistanceBetween(a,b);

distance will be the distance in meters .
