Use the Azure Maps map control

The Map Control client-side JavaScript library allows you to render maps and embedded Azure Maps functionality into your web or mobile application.

Prerequisites

To use the Map Control in a web page, you must have one of the following prerequisites:

Create a new map in a web page

You can embed a map in a web page by using the Map Control client-side JavaScript library.

  1. Create a new HTML file.

  2. Load in the Azure Maps Web SDK. You can choose one of two options;

    • Use the globally hosted CDN version of the Azure Maps Web SDK by adding references to the JavaScript and stylesheet in the <head> element of the HTML file:

      <link rel="stylesheet" href="https://atlas.microsoft.com/sdk/javascript/mapcontrol/2/atlas.min.css" type="text/css">
      <script src="https://atlas.microsoft.com/sdk/javascript/mapcontrol/2/atlas.min.js"></script>
      
    • Load the Azure Maps Web SDK source code locally using the azure-maps-control NPM package and host it with your app. This package also includes TypeScript definitions.

    npm install azure-maps-control

    Then add references to the Azure Maps stylesheet to the <head> element of the file:

    <link rel="stylesheet" href="https://atlas.microsoft.com/sdk/javascript/mapcontrol/2/atlas.min.css" type="text/css" />
    

    Note

    Typescript definitions can be imported into your application by adding the following code:

    import * as atlas from 'azure-maps-control';
    
  3. To render the map so that it fills the full body of the page, add the following <style> element to the <head> element.

     <style>
         html, body {
             margin: 0;
         }
    
         #myMap {
             height: 100vh;
             width: 100vw;
         }
     </style>
    
  4. In the body of the page, add a <div> element and give it an id of myMap.

     <body onload="InitMap()">
         <div id="myMap"></div>
     </body>
    
  5. Now, we'll initialize the map control. In order to authenticate the control, you'll either need to own an Azure Maps subscription key or use Azure Active Directory (AAD) credentials with authentication options.

    If you're using a subscription key for authentication, copy and paste the following script element inside the <head> element, and below the first <script> element. Replace <Your Azure Maps Key> with your Azure Maps primary subscription key.

    <script type="text/javascript">
       function InitMap()
       {
           var map = new atlas.Map('myMap', {
               center: [-122.33, 47.6],
               zoom: 12,
               language: 'en-US',
               authOptions: {
                   authType: 'subscriptionKey',
                   subscriptionKey: '<Your Azure Maps Key>'
               }
           }
       });
    </script>
    

    If you're using Azure Active Directory (AAD) for authentication, copy and paste the following script element inside the <head> element, and below the first <script> element.

    <script type="text/javascript">
      function InitMap()
      {
          var map = new atlas.Map('myMap', {
              center: [-122.33, 47.6],
              zoom: 12,
              language: 'en-US',
              authOptions: {
                  authType: 'aad',
                  clientId: '<Your AAD Client Id>',
                  aadAppId: '<Your AAD App Id>',
                  aadTenant: '<Your AAD Tenant Id>'
              }
          }
      });
    </script>
    

    For more information about authentication with Azure Maps, see the Authentication with Azure Maps document. Also, a list of samples showing how to integrate Azure Active Directory (AAD) with Azure Maps can be found here.

    Tip

    In this example, we've passed in the id of the map <div>. Another way to do this is to pass in the HTMLElement object by passingdocument.getElementById('myMap') as the first parameter.

  6. Optionally, you may find it helpful to add the following meta elements to the head element of the page:

     <!-- Ensures that IE and Edge uses the latest version and doesn't emulate an older version -->
     <meta http-equiv="x-ua-compatible" content="IE=Edge">
    
     <!-- Ensures the web page looks good on all screen sizes. -->
     <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
    
  7. Putting it all together, your HTML file should look something like the following markup:

     <!DOCTYPE html>
     <html>
     <head>
         <title></title>
    
         <meta charset="utf-8">
    
         <!-- Ensures that IE and Edge uses the latest version and doesn't emulate an older version -->
         <meta http-equiv="x-ua-compatible" content="IE=Edge">
    
         <!-- Ensures the web page looks good on all screen sizes. -->
         <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
    
         <!-- Add references to the Azure Maps Map control JavaScript and CSS files. -->
         <link rel="stylesheet" href="https://atlas.microsoft.com/sdk/javascript/mapcontrol/2/atlas.min.css" type="text/css">
         <script src="https://atlas.microsoft.com/sdk/javascript/mapcontrol/2/atlas.min.js"></script>
    
    
         <script type="text/javascript">
             //Create an instance of the map control and set some options.
             function InitMap()
             {
                 var map = new atlas.Map('myMap', {
                     center: [-122.33, 47.6],
                     zoom: 12,
                     language: 'en-US',
                     authOptions: {
                         authType: 'subscriptionKey',
                         subscriptionKey: '<Your Azure Maps Key>'
                     }
                 });
             }
         </script>
    
         <style>
             html, body {
                 margin: 0;
             }
    
             #myMap {
                 height: 100vh;
                 width: 100vw;
             }
         </style>
     </head>
     <body onload="InitMap()">
         <div id="myMap"></div>
     </body>
     </html>
    
  8. Open the file in your web browser and view the rendered map. It should look like the image below:

Localizing the map

Azure Maps provides two different ways of setting the language and regional view for the rendered map. The first option is to add this information to the global atlas namespace, which will result in all map control instances in your app defaulting to these settings. The following sets the language to French ("fr-FR") and the regional view to "Auto":

atlas.setLanguage('fr-FR');
atlas.setView('Auto');

The second option is to pass this information into the map options when loading the map like this:

map = new atlas.Map('myMap', {
    language: 'fr-FR',
    view: 'Auto',

    authOptions: {
        authType: 'aad',
        clientId: '<Your AAD Client Id>',
        aadAppId: '<Your AAD App Id>',
        aadTenant: '<Your AAD Tenant Id>'
    }
});

Note

It is possible to load multiple map instances on the same page with different language and region settings. Additionally, these settings can be updated after the map loads using the setStyle function of the map.

Here is an example of Azure Maps with the language set to "fr-FR" and the regional view set to "Auto".

A complete list of supported languages and regional views is documented here.

Azure Government cloud support

The Azure Maps Web SDK supports the Azure Government cloud. All JavaScript and CSS URLs used to access the Azure Maps Web SDK remain the same. The following tasks will need to be done to connect to the Azure Government cloud version of the Azure Maps platform.

When using the interactive map control, add the following line of code before creating an instance of the Map class.

atlas.setDomain('atlas.azure.us');

Be sure to use Azure Maps authentication details from the Azure Government cloud platform when authenticating the map and services.

When using the services module, the domain for the services needs to be set when creating an instance of an API URL endpoint. For example, the following code creates an instance of the SearchURL class and points the domain to the Azure Government cloud.

var searchURL = new atlas.service.SearchURL(pipeline, 'atlas.azure.us');

If directly accessing the Azure Maps REST services, change the URL domain to atlas.azure.us. For example, if using the search API service, change the URL domain from https://atlas.microsoft.com/search/ to https://atlas.azure.us/search/.
