Functions

addImageTemplate(string, string, boolean)	Adds an image template to the atlas namespace.
clearPrewarmedResources()	Clears up resources that have previously been created by atlas.prewarm(). Note that this is typically not necessary. You should only call this function if you expect the user of your app to not return to a Map view at any point in your application.
getAllImageTemplateNames()	Retrieves an array of names for all image templates that are available in the atlas namespace.
getAuthenticationOptions()	Gets the default authentication options that were provided. If not previously set all properties will be undefined.
getDomain()	Gets the default domain that was provided. If not previously set the default value is "atlas.microsoft.com".
getImageTemplate(string, number)	Retrieves an SVG template by name.
getLanguage()	Gets the default language that was provided. If not previously set the default value is "NGT".
getMaxParallelImageRequests()	Gets the Maximum number of images (raster tiles, sprites, icons) to load in parallel
getSessionId()	Gets the default session id that was provided. If not previously set the default value is a random UUID.
getSubscriptionKey()	Gets the default Azure Maps subscription key that was provided.
getUserRegion()
getVersion()	Current API version number based on build number.
getView()	Gets the default view setting of the map control. If not previously set the default value is undefined.
getWorkerCount()	Gets the worker count that will get created.
isSupported(boolean)	Checks to see if the user's browser is supported by the map control.
prewarm()	Initializes resources like WebWorkers that can be shared across maps to lower load times in some situations. atlas.setWorkerCount, if being used, must be set before prewarm() is called to have an effect. By default, the lifecycle of these resources is managed automatically, and they are lazily initialized when a Map is first created. By invoking prewarm(), these resources will be created ahead of time, and will not be cleared when the last Map is removed from the page. This allows them to be re-used by new Map instances that are created later. They can be manually cleared by calling atlas.clearPrewarmedResources(). This is only necessary if your web page remains active but stops using maps altogether. This is primarily useful when using GL-JS maps in a single page app, wherein a user would navigate between various views that can cause Map instances to constantly be created and destroyed.
setAuthenticationOptions(AuthenticationOptions)	Sets your authentication options as the default options in the atlas namespace which is used by the map control and any modules that make requests to the Azure maps services. If a Map is initialized with the authentication options explicitly defined and setAuthenticationOptions hasn't previously been called it will automatically be called by the Map constructor.
setDomain(string)	Sets the default domain used by the map and service modules unless the domain is explicitly specified when using those parts of the API. If a Map is initialized with the domain explicitly defined and setDomain hasn't previously been called it will automatically be called by the Map constructor. If the protocol is not specified https is assumed.
setLanguage(string)	Sets the default language used by the map and service modules unless the language is explicitly specified when using those parts of the API. If a Map is initialized with the language explicitly defined and setLanguage hasn't previously been called it will automatically be called by the Map constructor.
setMaxParallelImageRequests(number)	Sets Maximum number of images (raster tiles, sprites, icons) to load in parallel, which affects performance in raster-heavy maps. 16 by default.
setSessionId(string)	Sets the default session id used by the map and service modules unless the session id is explicitly specified when using those parts of the API. If a Map is initialized with the session ID explicitly defined and setSessionId hasn't previously been called it will automatically be called by the Map constructor.
setSubscriptionKey(string)	Sets your Azure Maps subscription key as the default subscription key in the atlas namespace which is used by the map control and any modules that make requests to the Azure maps services. If a Map is initialized with the subscription key explicitly defined and setSubscriptionKey hasn't previously been called it will automatically be called by the Map constructor.
setUserRegion(string)
setView(string)	Specifies which set of geopolitically disputed borders and labels are displayed on the map. The View parameter (also referred to as “user region parameter”) is a 2-letter ISO-3166 Country Code that will show the correct maps for that country/region. Country/Regions that are not on the View list or if unspecified will default to the “Unified” View. Please see the supported [Views]{@link https://aka.ms/AzureMapsLocalizationViews }. It is your responsibility to determine the location of your users, and then set the View parameter correctly for that location. The View parameter in Azure Maps must be used in compliance with applicable laws, including those regarding mapping, of the country/region where maps, images and other data and third party content that You are authorized to access via Azure Maps is made available.
setWorkerCount(number)	Sets number of web workers instantiated on a page. By default, it is set to half the number of CPU cores (capped at 6).
