The Maps JavaScript API features four basic map types (roadmap, satellite, hybrid, and terrain) which you can modify using layers and styles, controls and events, and various services and libraries. AudienceThis documentation is designed for people familiar with JavaScript programming and object-oriented programming concepts. You should also be familiar with Google Maps from a user's point of view. There are many JavaScript tutorials available on the Web. This conceptual documentation is designed to let you quickly start exploring and developing applications with the Maps JavaScript API. We also publish the Maps JavaScript API Reference. Hello, WorldThe easiest way to start learning about the Maps JavaScript API is to see a simple example. The following example displays a map centered on Sydney, New South Wales, Australia.

These steps are explained below. Declaring your application as HTML5We recommend that you declare a true Most current browsers will render content that is declared with this 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 This CSS declaration indicates that the map container The Maps JavaScript API is loaded using a To load the Maps JavaScript API inline in an HTML file, add a To dynamically load the Maps JavaScript API inline using a separate JavaScript file, see the example below. This approach allows you to handle all of your code

package can be imported into the application with: The loader exposes a Promise and callback interface. The following demonstrates usage of the default Promise method Notice in the
examples above that several attributes are set on the When loading the Maps JavaScript API via the URL you may optionally load additional
libraries through use of the In the This will probably slow your page load. But it means you can write subsequent script tags assuming that the API is already loaded. For the map to display on a web page, we must reserve a spot for it. Commonly, we do
this by creating a named 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 There are two required options for every map: The initial resolution at which to display the map is set by the 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: 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 map and tile coordinates. The JavaScript class that represents a

This behavior typically indicates issues with either an API key or billing. In order to use Google Maps Platform products, billing must be enabled

check if a billing account is attached to your project. Go to the Billing page in the Google Cloud Console and select the project under which your API key was created. To confirm the key is associated with the project: Once you have located your project in the Cloud Console, check if a billing account is attached by navigating to the Billing section in the left side menu. Go to the Enable Billing page in the Cloud Console and add a billing account to your project. For additional information, see Get Started with Google Maps
Platform. Great! Let’s make sure the provided billing method is valid. You can add, remove, or update a payment method in the Cloud Console. If you have set a daily
limit on any of your APIs, which is common to prevent unexpected increases, you can resolve this by increasing your daily limit. You can check your daily limits by going to the APIs & Services Dashboard in the Cloud Console.
Once there: API keys with an IP addresses restriction can only be used with web services that are intended for use from the server side (such as the
Geocoding API and other Web Service APIs). Most of these web services have equivalent services within the Maps JavaScript API (for example, see the Geocoding Service). To use the Maps JavaScript API client side services,
you will need to create a separate API key which can be secured with an HTTP referrers restriction (see Get, add, and restrict an API key). To help you get your maps code
