How do I download layers in The National Map Viewer?

Base map data layers in The National Map Viewer are for viewing only. This application is designed for visualizing data, combining different data layers, and creating (and printing) your own maps.

To download data from The National Map, see the link at the top of the Viewer for the Data Downloader.  None of the base map layers in the Viewer are available for download, but some of them can be accessed as a map service.
