Polygon With Hole

This example creates a polygon with an inner hole, by defining an inner path wound in the opposite direction to the outer path. Note that you can also use the Data layer, which offers a simpler way of creating holes because it handles the order of the inner and outer paths for you.

Read the documentation.

JavaScript

// This example creates a triangular polygon with a hole in it.

function initMap() {
  var map = new google.maps.Map(document.getElementById("map"), {
    zoom: 5,
    center: { lat: 24.886, lng: -70.268 }
  });

  // Define the LatLng coordinates for the polygon's  outer path.
  var outerCoords = [
    { lat: 25.774, lng: -80.19 },
    { lat: 18.466, lng: -66.118 },
    { lat: 32.321, lng: -64.757 }
  ];

  // Define the LatLng coordinates for the polygon's inner path.
  // Note that the points forming the inner path are wound in the
  // opposite direction to those in the outer path, to form the hole.
  var innerCoords = [
    { lat: 28.745, lng: -70.579 },
    { lat: 29.57, lng: -67.514 },
    { lat: 27.339, lng: -66.668 }
  ];

  // Construct the polygon, including both paths.
  var bermudaTriangle = new google.maps.Polygon({
    paths: [outerCoords, innerCoords],
    strokeColor: "#FFC107",
    strokeOpacity: 0.8,
    strokeWeight: 2,
    fillColor: "#FFC107",
    fillOpacity: 0.35
  });
  bermudaTriangle.setMap(map);
}

CSS

/* 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. */

body {
