Arrows (Symbols)

Read the documentation or view this example full screen.

// This example adds a predefined symbol (an arrow) to a polyline.
// Setting offset to 100% places the arrow at the end of the line.

function initMap() {
  var map = new google.maps.Map(document.getElementById('map'), {
    zoom: 6,
    center: {lat: 20.291, lng: 153.027},
    mapTypeId: 'terrain'
  });

  // Define a symbol using a predefined path (an arrow)
  // supplied by the Google Maps JavaScript API.
  var lineSymbol = {
    path: google.maps.SymbolPath.FORWARD_CLOSED_ARROW
  };

  // Create the polyline and add the symbol via the 'icons' property.
  var line = new google.maps.Polyline({
    path: [{lat: 22.291, lng: 153.027}, {lat: 18.291, lng: 153.027}],
    icons: [{
      icon: lineSymbol,
      offset: '100%'
    }],
    map: map
  });
}
<div id="map"></div>
/* Always set the map height explicitly to define the size of the div
 * element that contains the map. */
#map {
  height: 100%;
}
/* Optional: Makes the sample page fill the window. */
html, body {
  height: 100%;
  margin: 0;
  padding: 0;
}
 <!-- Replace the value of the key parameter with your own API key. -->
