All map symbols and overlay details can be reviewed in Map Legend and Overlay Details, which is accessible through the 'Map Menu'. Items displayed on the Map Legend and Overlay Details are dependent on which basemap and overlay is selected (for example, if the 'Topo' basemap layer is disabled, the Topo Scale will not be displayed on the Map Legend).

The Topo Scale serves as a legend for the various shades of colors representing land elevation. It may be viewed by opening the Map Legend.
