Removing Overlays

This example creates a ground overlay on top of a map, and adds a UI control allowing users to remove the ground overlay from the map.

Read the documentation.

TypeScript

// This example adds a UI control allowing users to remove the
// ground overlay from the map.

let historicalOverlay: google.maps.GroundOverlay;
let map: google.maps.Map;

function initMap(): void {
  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
  );

  addOverlay();
}

function addOverlay() {
  historicalOverlay.setMap(map);
}

function removeOverlay() {
  historicalOverlay.setMap(null);
}

JavaScript

// This example adds a UI control allowing users to remove the
// ground overlay from the map.
let historicalOverlay;
let map;

function initMap() {
  map = new google.maps.Map(document.getElementById("map"), {
    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
  );
  addOverlay();
}

function addOverlay() {
  historicalOverlay.setMap(map);
}

function removeOverlay() {
  historicalOverlay.setMap(null);
}
