Ground Overlays

This example creates a ground overlay on top of a map.

// This example uses a GroundOverlay to place an image on the map
// showing an antique map of Newark, NJ.

var historicalOverlay;

function initMap() {
  var map = new google.maps.Map(document.getElementById('map'), {
    zoom: 13,
    center: {lat: 40.740, lng: -74.18}
  });

  var imageBounds = {
    north: 40.773941,
    south: 40.712216,
    east: -74.12544,
    west: -74.22655
  };

  historicalOverlay = new google.maps.GroundOverlay(
      'https://www.lib.utexas.edu/maps/historical/newark_nj_1922.jpg',
      imageBounds);
  historicalOverlay.setMap(map);
}

<div id="map"></div>

/* Always set the map height explicitly to define the size of the div
 * element that contains the map. */
