L.Geometryutil.Distance – Calculate Distance To Linestring

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

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: “© OpenStreetMap contributors”}).addTo(map);var marker = L.marker(center).addTo(map);L.circle(marker.getLatLng(), { color: “red”, fillColor: “#f03”, fillOpacity: 0.2, radius: radiusInKm * 1000}).addTo(map);var to = L.GeometryUtil.destination(marker.getLatLng(), angleInDegrees, radiusInKm * 1000);L.marker(to).addTo(map);html, body { height: 100%; margin: 0;}#map { width: 100%; height: 100%;}

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