Data Layer: Polygon

This example uses the Data layer to create a polygon with two internal holes. If you don't use the data layer to create an inner hole, you must define a path wound in the opposite direction to the outer path as shown in this alternative.

Read the documentation.

JavaScript

// This example uses the Google Maps JavaScript API's Data layer
// to create a rectangular polygon with 2 holes in it.

function initMap() {
  var map = new google.maps.Map(document.getElementById("map"), {
    zoom: 6,
    center: { lat: -33.872, lng: 151.252 }
  });

  // Define the LatLng coordinates for the outer path.
  var outerCoords = [
    { lat: -32.364, lng: 153.207 }, // north west
    { lat: -35.364, lng: 153.207 }, // south west
    { lat: -35.364, lng: 158.207 }, // south east
    { lat: -32.364, lng: 158.207 } // north east
  ];

  // Define the LatLng coordinates for an inner path.
  var innerCoords1 = [
    { lat: -33.364, lng: 154.207 },
    { lat: -34.364, lng: 154.207 },
    { lat: -34.364, lng: 155.207 },
    { lat: -33.364, lng: 155.207 }
  ];

  // Define the LatLng coordinates for another inner path.
  var innerCoords2 = [
    { lat: -33.364, lng: 156.207 },
    { lat: -34.364, lng: 156.207 },
    { lat: -34.364, lng: 157.207 },
    { lat: -33.364, lng: 157.207 }
  ];

  map.data.add({
    geometry: new google.maps.Data.Polygon([
      outerCoords,
      innerCoords1,
      innerCoords2
    ])
  });
}
