Leaflet - create a marker with latLon + distance (meter) + angle (degree)

How to calculate a new point (marker B) at a given distance in meter from a marker A and at a given angle in degree?

Google API has this but I can't find it in Leaflet:

var pointA = new google.maps.LatLng(25.48, -71.26); var radiusInKm = 10; var pointB = pointA.destinationPoint(90, radiusInKm);

You can use the destination method of Leaflet.GeometryUtil to calculate the destination point and create a marker there :

var center = [40.69, -73.98]; var radiusInKm = 10; var angleInDegrees = 90; var A = L.marker(center).addTo(map); var B = L.GeometryUtil.destination(markerA.getLatLng(), angleInDegrees, radiusInKm * 1000); L.marker(B).addTo(map);

and a demo

<div class="snippet" data-lang="js" data-hide="true" data-console="false" data-babel="false"> <div class="snippet-code snippet-currently-hidden">

var center = [40.69,-73.98];
var radiusInKm = 10;
var angleInDegrees = 90;

var map = L.map('map').setView(center, 11);
L.tileLayer('http://{s}.tile.osm.org/{z}/{x}/{y}.png', {
    attribution: '&copy; <a href="http://osm.org/copyright">OpenStreetMap</a> contributors'

var marker = L.marker(center).addTo(map);
L.circle(marker.getLatLng(), {
    color: 'red',
    fillColor: '#f03',
    fillOpacity: 0.2,
    radius: radiusInKm * 1000

var to = L.GeometryUtil.destination(marker.getLatLng(), angleInDegrees, radiusInKm * 1000);

If you want to avoid an external library, you can take inspiration from the destination method source code (currently at line 712).
