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.

// 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: -80.190},
    {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: 29.570, 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);
}
