The author of a map selects the basemap that best fits the purpose of the map. However, you as the viewer of a map might want to see a different basemap with the same operational layers. The app lets you change the basemap of a map on the fly, without requiring an update to the map as it's written and stored on the online geographic information system (GIS).
To change the basemap of a map, follow these steps:
The Map Contents pivot displays on the layers panel.
The Select basemap page displays.
You are returned to the map, and it now displays the selected basemap.
