Maximum Zoom Imagery Service

This example creates a map of metropolitan Tokyo. If the user clicks on the map, a popup window indicates the maximum zoom level at that location.

Read the documentation.

JavaScript

var map;
var maxZoomService;
var infoWindow;

function initMap() {
  map = new google.maps.Map(document.getElementById("map"), {
    zoom: 11,
    center: { lat: 35.6894, lng: 139.692 },
    mapTypeId: "hybrid"
  });

  infoWindow = new google.maps.InfoWindow();

  maxZoomService = new google.maps.MaxZoomService();

  map.addListener("click", showMaxZoom);
}

function showMaxZoom(e) {
  maxZoomService.getMaxZoomAtLatLng(e.latLng, function(response) {
    if (response.status !== "OK") {
      infoWindow.setContent("Error in MaxZoomService");
    } else {
      infoWindow.setContent(
        "The maximum zoom at this location is: " + response.zoom
      );
    }
    infoWindow.setPosition(e.latLng);
    infoWindow.open(map);
  });
}

CSS

/* Always set the map height explicitly to define the size of the div
       * element that contains the map. */
#map {
  height: 100%;
}

/* Optional: Makes the sample page fill the window. */
html,
body {
  height: 100%;
  margin: 0;
  padding: 0;
}
