如何使用谷歌地图包在node.js中定义纬度和经度？

我尝试使用下面的代码来声明纬度和经度，请参阅： var origin1 但是它抛出 gs has no method 'LatLng' 你能建议我如何定义 LAtLng 吗？

         function calculateDistances() {
              var gs =require('googlemaps');
         //in next line i tried to define LAtLNG it throws gs has no method 'LatLng' 
             **var origin1 = gs.LatLng(13.125511084202,80.029651635576);**
         //Below code i tried in html
         var origin2 = new google.maps.LatLng(12.9898593006481,80.2497744326417);;
        var destinationA = new google.maps.LatLng(13.125511084202,80.029651635576);;
         var destinationB = new google.maps.LatLng(12.9898593006481,80.2497744326417);
     var service = new google.maps.DistanceMatrixService();
     service.getDistanceMatrix(
      {
     origins: [origin1, origin2],
    destinations: [destinationA, destinationB],
    travelMode: google.maps.TravelMode.DRIVING,
    unitSystem: google.maps.UnitSystem.METRIC,
    avoidHighways: false,
    avoidTolls: false
  }, callback);
  }
