Layers are the contents of a map. They include a wide range of information about people, the earth, life, and so on, and are composed of imagery, tiles, features, and more. To add layers to a map, sign in to your organization and open Map Viewer. You can search for layers in your content or organization, or public layers in ArcGIS Online. You can also add layers from a URL.
When you save a map, the layers you added are saved with it, and the map appears on the My Content tab of the Content page.
The following table shows the layers you can add to a map and the method to use to add them. When you save the map, any items you've added are saved with the map and the map appears on the My Content tab on the content page.
