For layers you have added from ArcGIS or layers you have shared on ArcGIS, you can access information about the item on ArcGIS. The information associated with the layer may include a description, access use and constraints, tags, credits, size, and extent.
- On the Contents pane, select the desired layer.
- Click the Layer details button at the bottom of the Contents pane.
If the Layer details button isn't enabled, the selected layer does not have information accessible from ArcGIS
The ArcGIS details page for the layer opens in your default web browser. If you are viewing the details for a layer that is not shared publically, you are prompted to log in to ArcGIS
