Calculate endpoint given distance, bearing, starting point

Question

I am trying to find the destination point, given a starting point lat/long, bearing & distance. The calculator from this website below gives me the desired results.

Answer 1

very simple solution in geometry library (V3), if you do not have a problema with using the google maps api V3 (depending on the application - realtime asset tracking, for example - the free license is not applicable OR you might not want to refactor from V2 to V3).

1st: declare an extra library ALONG with your current declaration:

2nd: establish starting point, heading and distance

var nyc = new google.maps.LatLng(40.715, -74.002);
var distance = 5576673;
var heading = 51.2145;

3rd: go there

var endPoint = google.maps.geometry.spherical.computeOffset(nyc, distance, heading);
var london = new google.maps.Marker({
  position: endPoint,
  map: map
});

done, you are now in London town. for more info regarding computeDistance, computeHeading and computeArea:
