Just about all of us use ArcGIS Living Atlas every day. Living Atlas basemaps are the foundation for almost every map or app, whether used in your browser or device. Additionally, Living Atlas layers, such as live feeds, environmental layers, demographic information, and more, complement and add context to your operational layers.
Most of us discover Living Atlas content when we use basemaps or search for layers in Map Viewer. But there's a way you can integrate the Living Atlas website directly into your workflows.
If you sign in to your account at the Living Atlas website, you can open the Browse tab to search for layers to begin authoring maps and scenes.

Since you're signed in, you can also use My Favorites to bookmark Living Atlas items for quick access, or (if an administrator) can also share creative Living Atlas basemaps into your organization's custom basemap gallery.
