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.
TypeScript
let map: google.maps.Map;
let maxZoomService: google.maps.MaxZoomService;
let infoWindow: google.maps.InfoWindow;

});
infoWindow = new google.maps.InfoWindow();
maxZoomService = new google.maps.MaxZoomService();
map.addListener("click", showMaxZoom);
}
function showMaxZoom(e: google.maps.MapMouseEvent) {

e.latLng,
