Azure Maps Leaflet plugin

A leafletjs plugin that makes it easy to overlay tile layers from the Azure Maps tile services.

Features:

  • Authenticate using an Azure Maps subscription key or Azure Active Directory.
  • Works with with Azure Public and Government clouds.
  • Supports over 30 languages
  • Supported layers:
    • Road maps
      • Main (microsoft.base.road) - All layers with our main style.
      • Labels (microsoft.base.labels.road) - Label data in our main style.
      • Hybrid (microsoft.base.hybrid.road) - Road, boundary and label data in our main style.
      • Dark grayscale (microsoft.base.darkgrey) - All layers with our dark grayscale style.
    • Imagery (microsoft.imagery)
    • Traffic Flow
      • absolute (microsoft.traffic.flow.absolute)
      • reduced-sensitivity (microsoft.traffic.flow.reduced-sensitivity)
      • relative (microsoft.traffic.flow.relative)
      • relative-delay (microsoft.traffic.flow.relative-delay`)
    • Traffic Incident

If using Azure Government cloud, set the Azure Maps domain to 'atlas.azure.us' when creating the layer.

//When using the static function to create a layer.
L.tileLayer.azureMaps({ 
    authOptions: {
        azMapsDomain: 'atlas.azure.us'    
        //Your other authentication options.
    }
}).addTo(map);

//When creating an instance of the Azure Maps tile layer class.
var layer = new L.TileLayer.AzureMaps({ 
    authOptions: {
        azMapsDomain: 'atlas.azure.us'    
        //Your other authentication options.
    }
}});

More details on authentication options for Azure Maps is documented here.

AuthenticationOptions interface

Authentication options for connecting to the Azure Maps tile services.

Properties

Name Type Description
aadAppId string The Azure AD registered app ID. This is the app ID of an app registered in your Azure AD tenant. Must be specified for AAD authentication type.
aadInstance string The AAD instance to use for logging in. Can be optionally specified when using the AAD authentication type. By default the https://login.microsoftonline.com/ instance will be used.
aadTenant string The AAD tenant that owns the registered app specified by aadAppId. Must be specified for AAD authentication type.
authContext AuthenticationContext Optionally provide an existing AuthenticationContext from the ADAL.js library. This authentication context will be used to acquire the AAD token. Only used with the AAD authentication type. This auth context must be configured to use the same AAD app ID as this.aadAppId. If this is not provided all map instances will share their own private auth context.
authType 'subscriptionKey' | 'aad' | 'anonymous' The authentication mechanism to be used.
azMapsDomain string A URL string pointing to the domain of the Azure Maps service, default is 'atlas.microsoft.com'. Set to 'atlas.azure.us' if using the US Azure Government cloud.
clientId string The Azure Maps client ID, This is an unique identifier used to identify the maps account. Preferred to always be specified, but must be specified for AAD and anonymous authentication types.
getToken (resolve: (value?: string) => void, reject: (reason?: any) => void) => void A callback to use with the anonymous authentication mechanism. This callback will be responsible for resolving to a authentication token. E.g. fetching a CORS protected token from an endpoint.
subscriptionKey string Subscription key from your Azure Maps account. Must be specified for subscription key authentication type.

'microsoft.traffic.flow.relative-delay' Custom tileset ID's that return raster tiles that are 256x256 pixels in size can also be specified as a string. Default 'microsoft.base.road'
timeStamp string | Date The desired date and time of the requested tile. This parameter must be specified in the standard date-time format (e.g. 2019-11-14T16:03:00-08:00), as defined by ISO 8601. This parameter is only supported when tilesetId parameter is set to microsoft.weather.infrared.main or microsoft.weather.radar.main.
trafficFlowThickness number The thickness of lines when using the traffic flow tilesets. Default: 5
view string Geopolitical view of the map. Supported views Default: 'Auto'

Alternative Option for Leaflet

This Leaflet plugin makes it easy to overlay tile layers from Azure Maps using any of the supported authentication methods available in Azure Maps; subscription key or Azure Active Directory (recommended). If you are only using a subscription key and don't plan to use Azure Active Directory, the following code can be used instead to easily overlay Azure Maps tile layers on a leaflet map without having to use this plugin.
