The Map Object

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

The JavaScript class that represents a map is the class.
Objects of this class define a single map on a page. (You may create more
than one instance of this class — each object will define a separate
map on the page.) We create a new instance of this class using the JavaScript

When you create a new map instance, you specify a
HTML element in the page as a container for the map. HTML nodes
are children of the JavaScript object, and
we obtain a reference to this element via the

This code defines a variable (named ) and assigns that
variable to a new object. The function is
known as a constructor and its definition is shown below:

Constructor Description
Creates a new map inside of the given HTML container — which is
typically a DIV element — using any (optional) parameters that
are passed.

Delete Location History

You can delete all or part of your Location History.Important: When you delete information from Timeline, it’s permanent. You won’t be able to see your Location History information on Timeline again. If you have other settings like Web & App Activity turned on and you delete Location History, you may still have location data saved in your Google Account as part of your use of other Google sites, apps, and services. For example, location data may be saved as part of activity on Search and Maps when your Web & App Activity setting is on, and included in your photos depending on your camera app settings.
To delete Location History, follow the steps below.

  1. On your computer, go to Timeline.
  2. In the bottom right, click Delete . You can also click Settings ​  Delete all location history.
  3. Click Delete location history.

Automatically delete your Location History

You can choose to automatically delete Location History that’s older than 3 months or 18 months.

  1. On your computer, go to Timeline.
  2. At the bottom right, click Settings  Automatically delete Location History.
  3. Follow the on-screen instructions.

Universal cross-platform syntax

As a developer of an Android app, an iOS app, or a website, you can construct a common URL,
and it will open Google Maps and perform the requested action, no matter the platform in
use when the map is opened.

  • On an Android device:
    • If
      Google Maps app for Android is installed and active, the URL launches
      Google Maps in the Maps app and performs the requested action.
    • If the Google Maps app is not installed or is disabled, the URL launches
      Google Maps in a browser and performs the requested action.
  • On an iOS device:
    • If Google Maps app for iOS
      is installed, the URL launches Google Maps in the Maps app and performs
      the requested action.
    • If the Google Maps app is not installed, the URL launches
      Google Maps in a browser and performs the requested action.
  • On any other device, the URL launches Google Maps in a browser and
    performs the requested action.

It is recommended that you use a cross-platform URL to launch Google Maps from your app
or website, since these universal URLs allow for broader handling of the maps requests
no matter the platform in use. For features that may only be functional on a mobile
platform (for example, turn-by-turn navigation), you may prefer to use a platform-specific
option for Android or iOS. See the following documentation:

  • Google Maps Intents for Android — specifically to launch the

    Google Maps app for Android

  • Google Maps URL Scheme for iOS — specifically to launch the
    Google Maps app for iOS

API Key and Billing Errors

Under certain circumstances, a darkened map, or ‘negative’ Street View image,
watermarked with the text «for development purposes only», may be displayed.
This behavior typically indicates issues with either an API key or billing.
In order to use Google Maps Platform products, billing must be enabled on your account,
and all requests must include a valid API key. The following flow will help troubleshoot this:

If your code isn’t working:

To help you get your maps code up and running, Brendan Kenny and Mano Marks point out
some common mistakes and how to fix them in this video.

  • Look for typos. Remember that JavaScript is a case-sensitive
  • Check the basics — some of the most common problems occur with the
    initial map creation. Such as:
    • Confirm that you’ve specified the
      and properties in your map
    • Ensure that you have declared a div element in which the map will
      appear on the screen.
    • Ensure that the div element for the map has a height. By default,
      div elements are created with a height of 0, and are therefore

    Refer to our examples for a

  • Use a JavaScript debugger to help identify problems, like the one available
    in the Chrome
    Developer Tools. Start by looking in the JavaScript console for errors.
  • Post questions to Stack
    Overflow. Guidelines on how to post great questions are available on
    the Support page.

Loading the Maps JavaScript API

Script Tag Attributes

  • : The URL where the Maps JavaScript API is loaded from,
    including all of the symbols and definitions you need for using the Maps JavaScript API.
    The URL in this example has two parameters: , where you
    provide your API key, and , where you specify the name
    of a global function to be called once the Maps JavaScript API
    loads completely. Read more about URL parameters.
  • : Asks the browser to parse the HTML document first before loading the script.
    When the script is executed, it will call the function specified using the


We think security on the web is pretty important, and recommend using HTTPS
whenever possible. As part of our efforts to make the web more secure, we’ve
made all of the Maps JavaScript API available over HTTPS. Using HTTPS
encryption makes your site more secure, and more resistant to snooping or tampering.

We recommend loading the Maps JavaScript API over HTTPS using the
tag provided above.

If required, you can load the Maps JavaScript API over HTTP by
requesting .


When loading the Maps JavaScript API via the URL you may optionally
load additional libraries through use of the
URL parameter. Libraries are modules of code that
provide additional functionality to the main Maps JavaScript API but are not
loaded unless you specifically request them. For more
information, see
Libraries in the Maps JavaScript API.

Synchronously loading the API

In the tag that loads the Maps JavaScript API,
it is possible to omit the attribute and the
parameter. This will cause the loading of the API to block until the API is

This will probably slow your page load. But it means you can write
subsequent script tags assuming that the API is already loaded.

let map;

function initMap() {
map = new google.maps.Map(document.getElementById(«map»), {

/* Always set the map height explicitly to define the size of the div
* element that contains the map. */

Even in this simple example, there are a few things to note:

  1. We declare the application as HTML5 using the declaration.
  2. We create a element named «map» to hold the

  4. We load the Maps JavaScript API using a tag.

These steps are explained below.

Map Options

There are two required options for every map: and

map = new google.maps.Map(document.getElementById('map'), {
  center: {lat: -34.397, lng: 150.644},
  zoom: 8

Zoom Levels

The initial resolution at which to display the map is set by the
property, where zoom
corresponds to a map of the Earth fully zoomed out, and larger zoom levels
zoom in at a higher resolution. Specify zoom level as an integer.

zoom: 8

Offering a map of the entire Earth as a single image would either
require an immense map, or a small map with very low resolution. As
a result, map images within Google Maps and the Maps JavaScript API
are broken up into map «tiles» and «zoom levels.» At low zoom levels, a small set of
map tiles covers a wide area; at higher zoom levels, the tiles are of
higher resolution and cover a smaller area. The following list shows the
approximate level of detail you can expect to see at each zoom level:

  • 1: World
  • 5: Landmass/continent
  • 10: City
  • 15: Streets
  • 20: Buildings

The following three images reflect the same location of Tokyo
at zoom levels 0, 7 and 18.

For information on how the Maps JavaScript API loads
tiles based on the current zoom level, see the guide to

Двигаться легко

На вашем пути больше не будет никаких преград. Одна из главных особенностей сервиса, идеально подходящая для жителей крупных городов, — интерактивное отслеживание ситуации на дорогах. В отличие от остальных навигаторов, Гугл-карты не просто строят статичный маршрут.

Детализация маршрута с гугл картами

Приложение умеет не просто анализировать дорожную загрузку, но и менять результаты в соответствии с полученной информацией. Если ваш маршрут пролегает по дороге, которая сейчас стоит вследствие крупной аварии, приложение порекомендует вам перестроить путь и проехаться по маленькой боковой улочке.

Вы также можете изменить путь самостоятельно. Если автомобилисты в соседней пробке при помощи чата порекомендовали вам проехать под мостом, скорректируйте выстроенный маршрут в соответствии с их советами.

На шаг впереди

Нередко начинающие автолюбители неуверенно чувствуют себя на дороге

Все их внимание уходит на отслеживание текущей ситуации. Времени следить за маршрутом уже не остается

Из-за этого новички нередко пропускают нужный поворот или съезд, вынуждены терять время, перестраиваться в другой ряд и возвращаться.

Гугл карты помогут проложить обратный маршрут

С Гугл-картами такая проблема исчезает. В приложении есть возможность включить опцию пошаговой навигации. В этом случае сервис будет заранее сообщать вам, что через несколько метров нужно повернуть направо. На карте появится крупная отметка, а роботизированный голос будет регулярно напоминать вам о повороте.

Помимо этого, в сервисе присутствует интерактивный выбор полосы движения. Сайт порекомендует, в какой ряд лучше перестроиться, и даст совет в зависимости от сделанного выбора.

Declaring your application as HTML5

We recommend that you declare a true
within your web application. Within the examples here, we’ve
declared our applications as HTML5 using the simple HTML5
as shown below:

<!DOCTYPE html>

Most current browsers will render content that is declared with this
in «standards mode» which means that your application
should be more cross-browser compliant. The is also
designed to degrade gracefully; browsers that don’t understand it will ignore
it, and use «quirks mode» to display their content.

Note that some CSS that works within quirks mode is not valid in
standards mode. In specific, all percentage-based sizes must inherit
from parent block elements, and if any of those ancestors fail to
specify a size, they are assumed to be sized at 0 x 0 pixels. For
that reason, we include the following

  #map {
    height: 100%;
  html, body {
    height: 100%;
    margin: 0;
    padding: 0;

This CSS declaration indicates that the map container

(with id ) should take up 100% of the height of the HTML
body. Note that we must specifically declare those percentages for
and as well.

See your travels

You can see how far you travelled and the way you travelled from place to place, like walking, biking, driving, or public transportation. Whether Timeline measures distances in miles or kilometers is based on your country.

  1. On your computer, open Google Maps.
  2. Sign in with the same Google Account you use on your mobile device.
  3. In the top left, click Menu .
  4. Click Timeline .
  5. To see another date, at the top, choose a day, month, and year.

Tip: To see places that you’ve visited recently, click Menu Your places Visited.

See your home and work on Timeline

If you’ve saved your home and work addresses, they’ll show up on Timeline. In addition to Timeline, this information may also be used in other Google products and services.

Learn how to set your home and work addresses.

Map DOM Elements

<div id="map"></div>

For the map to display on a web page, we must reserve a spot for it.
Commonly, we do this by creating a named element and
obtaining a reference to this element in the browser’s document object model

In the example above, we used CSS to set the height of the map div to
«100%». This will expand to fit the size on mobile devices. You may need to
adjust the width and height values based on the browser’s screensize and
padding. Note that divs usually take their width from their containing
element, and empty divs usually have 0 height. For this reason, you must
always set a height on the explicitly.

Launch Google Maps and perform a specific action

To launch Google Maps and optionally perform one of the supported functions,
use a URL scheme of one of the following forms, depending on the action requested:

  • — launch a Google Map that displays a pin for a specific place, or perform
    a general search and launch a map to display the results:

  • — request directions and launch Google Maps with the results:

  • — launch Google Maps with no markers or directions:

  • — launch an interactive panorama image:

Important: The parameter identifies the version of
Maps URLs this URL is intended for. This parameter is required in every
request. The only valid value is 1. If is NOT present in the URL,
all parameters are ignored and the default Google Maps app will launch, either
in a browser or the Google Maps mobile app, depending on the platform in use
(for example, https://www.google.com/maps).

Constructing valid URLs

You must properly encode URLs.

For example, some parameters use a pipe character
() as a separator, which you must encode as
in the final URL. Other parameters use comma-separated values, such as latitude/longitude
coordinates or City, State. You must encode the comma as . Encode spaces with
, or replace them with a plus sign ().

Additionally, URLs are limited to 2,048 characters for each request. Be aware of this limit
when constructing your URLs.
