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

TypeScript

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

let historicalOverlay;

function initMap(): void {
  const map = new google.maps.Map(
    document.getElementById("map") as HTMLElement,
    {
      zoom: 13,
      center: { lat: 40.74, lng: -74.18 }
    }
  );

  const 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);
}
