Google map api drawn polyline with encoded points

Question

I am new in javascript and Google map api, so i have encoded points like this: \"yzocFzynhVq}@n}@o}@nzD\" and trying to draw polyline with it, I haven\'t found topics or doc

Answer 1

See the geometry library documentation for decodePath

That will convert your encoded string into an array of google.maps.LatLng objects that can be used to create a Polyline

Working example

working code snippet:

function initialize() {
  var myLatLng = new google.maps.LatLng(24.886436490787712, -70.2685546875);
  var mapOptions = {
    zoom: 13,
    center: myLatLng,
    mapTypeId: google.maps.MapTypeId.TERRAIN
  };

  var bermudaTriangle;

  var map = new google.maps.Map(document.getElementById('map_canvas'),
    mapOptions);


  // Construct the polygon
  bermudaTriangle = new google.maps.Polygon({
    paths: google.maps.geometry.encoding.decodePath("yzocFzynhVq}@n}@o}@nzD"),
    strokeColor: '#FF0000',
    strokeOpacity: 0.8,
    strokeWeight: 2,
    fillColor: '#FF0000',
    fillOpacity: 0.35
  });

  bermudaTriangle.setMap(map);
  map.setCenter(bermudaTriangle.getPath().getAt(Math.round(bermudaTriangle.getPath().getLength() / 2)));
}
google.maps.event.addDomListener(window, 'load', initialize);

#map_canvas {

  #map_canvas {
