Description

The list of methods to do Distance Calculate are organized into topic(s).

Method

haversineDistance(lat1, lng1, lat2, lng2)

var haversineDistance(lat1, lng1, lat2, lng2) {
    var R = 6371; 
    var deltaLat = (lat2-lat1).inRadians();
    var deltaLng = (lng2-lng1).inRadians();
    var a = (Math.sin(deltaLat/2) * Math.sin(deltaLat/2)) + (Math.cos(lat1.inRadians()) * Math.cos(lat2.inRadians()) *
                   Math.sin(deltaLng/2) * Math.sin(deltaLng/2));
    var c = 2 * Math.atan2(Math.sqrt(a), Math.sqrt(1-a));
    return R * c;

haversineDistance(lat1, lon1, lat2, lon2)

function haversineDistance(lat1, lon1, lat2, lon2){
  var R = 6371; 
  var x1 = lat2-lat1;
  var dLat = x1.toRad();  
  var x2 = lon2-lon1;
  var dLon = x2.toRad();  
  var a = Math.sin(dLat/2) * Math.sin(dLat/2) + 
  Math.cos(lat1.toRad()) * Math.cos(lat2.toRad()) * 
  Math.sin(dLon/2) * Math.sin(dLon/2);
