ArcGISMap class final

A map is a container for layers. Use a map together with an ArcGISMapViewController to display layers of geographic data in 2D.

ArcGISMap contains layers of mapping data and information such as basemaps, popups, renderers, and labels which define the map's capabilities. You can access ArcGISMap content directly or visualize the map in an ArcGISMapViewController.

In an MVC architecture, ArcGISMap represents the model and ArcGISMapViewController represents the view. ArcGISMap specifies how the geographic data is organized, and ArcGISMapViewController renders the data on the screen and allows users to interact with it.

A map can contain a basemap and one or more operational layers:

• A basemap is a map layer that helps orient the user of the map. Typically it sits behind operational layers and shows roads and parcel boundaries to give context to operational layers. Basemaps can also contain layers which are drawn over the top operational layers such as label layers.
• An operational layer provides content that is of unique interest to the app and the task at hand, such as data about earthquakes, traffic, or weather. Its content might change frequently.

You can create a map from an existing web map using its URL or PortalItem. Alternatively, you can get a map directly from a MobileMapPackage.maps collection. ArcGISMap properties will be hydrated when the map is loaded.

If you create a new map, the spatial reference of the first layer you add, which is typically the first layer in the Basemap, defines the spatial reference of the entire map,
