ArcGIS Basemap

What is Basemap?

A Basemap provides a background of geographical context for the content you want to display on a map.

A basemap is used for locational reference and provides a framework on which users overlay or mash up their operational layers, perform tasks, and visualize Geographic information.

Basemap layers are a kind of map layer that provides a framework on to which you display your dynamic operational information.
