How to calculate distance between two points in google maps V3? If you want to calculate it yourself, then you can use the Haversine formula:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | var rad = function(x) { return x * Math.PI / 180; }; var getDistance = function(p1, p2) { var R = 6378137; // Earth’s mean radius in meter var dLat = rad(p2.lat() - p1.lat()); var dLong = rad(p2.lng() - p1.lng()); var a = Math.sin(dLat / 2) * Math.sin(dLat / 2) + Math.cos(rad(p1.lat())) * Math.cos(rad(p2.lat())) * Math.sin(dLong / 2) * Math.sin(dLong / 2); var c = 2 * Math.atan2(Math.sqrt(a), Math.sqrt(1 - a)); var d = R * c; return d; // returns the distance in meter }; |
