This example creates a ground overlay on top of a map.
Read the documentation.
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://storage.googleapis.com/geo-devrel-public-buckets/newark_nj_1922-661x516.jpeg", imageBounds ); historicalOverlay.setMap(map); } declare global { interface Window { initMap: () => void; } } window.initMap = initMap;
